DECISION AND DETERMINATION OF DISPUTE
BY MEMBERS LIEBMAN AND SCHAUMBER
This is a jurisdictional dispute proceeding under Sec-
tion 10(k) of the National Labor Relations Act (the Act).
CEMEX Construction Materials, L.P. (the Employer)
filed a charge on October 11, 2007,1 alleging that the
Respondent, International Longshore and Warehouse
Union, Local 10, AFL–CIO (ILWU or Local 10), vio-
lated Section 8(b)(4)(D) of the Act by engaging in pro-
scribed activity with an object of forcing the Employer to
assign certain work to employees it represents rather than
to employees represented by the International Union of
Operating Engineers, Local 3, AFL–CIO (Operating En-
gineers or Local 3). The hearing was held on November
2 and 5 before Hearing Officer Paula R. Katz. Thereaf-
ter, the Employer and Local 10 filed posthearing briefs.
The National Labor Relations Board affirms the hear-
ing officer’s rulings, finding them free from prejudicial
error. On the entire record, the Board makes the follow-
ing findings.2
I. JURISDICTION
During the 12 months ending October 31, the Employer
derived gross revenue in excess of $500,000 and pur-
chased and received at its facilities in California goods
valued in excess of $50,000 directly from points outside
the State of California. The parties stipulated, and we find,
that the Employer is engaged in commerce within the
meaning of Section 2(6) and (7) of the Act and that the
ILWU and the Operating Engineers are labor organiza-
tions within the meaning of Section 2(5) of the Act.
II. THE DISPUTE
A. Background and Facts of Dispute
The Employer produces ready-mix concrete using
sand, aggregate rock, and cement delivered to its batch
plant adjacent to Pier 92 in the Port of San Francisco,
1 Unless otherwise indicated, all dates refer to 2007.
2 Effective midnight December 28, 2007, Members Liebman,
Schaumber, Kirsanow, and Walsh delegated to Members Liebman,
Schaumber, and Kirsanow, as a three-member group, all of the Board’s
powers in anticipation of the expiration of the terms of Members Kir-
sanow and Walsh on December 31, 2007. Pursuant to this delegation,
Members Liebman and Schaumber constitute a quorum of the three-
member group. As a quorum, they have the authority to issue decisions
and orders in unfair labor practice and representation cases. See Sec.
3(b) of the Act.
California.3 In 2005, the Employer acquired RMC Pa-
cific Corporation, including RMC Pacific’s ready-mix
concrete operation on Mariposa Street in San Francisco.4
Sometime before 2005, RMC Pacific had begun making
arrangements for locating a new batch plant at one of the
piers in the Port of San Francisco because of planned
redevelopment of the area around the Mariposa Street
facility.
In 2006, the Employer began operating the new batch
plant on land leased from the Port of San Francisco adja-
cent to pier 92. Raw materials used to make the ready-
mix concrete were trucked to the pier 92 batch plant.
Trucks continue to deliver some of the raw materials, but
on September 21 the Employer also received a delivery
of sand and aggregate by barge. The barge was tied to
the dock adjacent to the pier 92 plant for unloading.5
The barge is unloaded by an employee operating a
front-end loader, also called a bucket loader, to scoop the
bulk material from the deck of the barge and put it into a
hopper located on the barge. The hopper deposits the
material onto a conveyer belt, which transports the mate-
rial into the batch plant for storage or to be directly
added to concrete being mixed.
The Employer assigned the operation of this front-end
loader to its employees represented by Local 3, who per-
form all the production work at the pier 92 batch plant.
As a member of the Aggregates and Concrete Associa-
tion, the Employer is bound by a collective-bargaining
agreement between the Bay Area Building Materials
Dealers and Local 3, commonly known as the Bay Area
Batch Plant Agreement, which covers the employees
working at the pier 92 batch plant.6 The Employer does
not employ any employees represented by Local 10 and
does not have a collective-bargaining agreement with
Local 10.
The president of Local 10 told the Employer that if any
work was to be performed by the Employer on its barge
at pier 92, that work belonged to Local 10. On Septem-
ber 21, Local 10 picketed the Employer at pier 92. The
picket signs read:
“CEMEX AND LOCAL #3
3 Concrete is a mixture of cement, water, aggregate rock, and sand.
Ready-mix concrete is a type of concrete produced in “batches” at a
batch plant by mixing different proportions of the materials to meet
particular specifications. The mixture is loaded into a transit mixer
mounted on a truck or barge for delivery to a jobsite, where it is poured.
4 The Mariposa Street facility is not located next to the water, so no
barge unloading was performed there.
5 At the time of the hearing, the Employer had received only one
barge delivery. Because of limited storage capacity at the pier 92 batch
plant, the Employer was using the barge as additional storage space.
6 The Employer also employs truck drivers, represented by the
Teamsters, who operate the ready-mix trucks that deliver the concrete,
and vehicle mechanics, represented by the Machinists, who service the
ready-mix trucks.

OPERATING ENGINEERS ARE INFRINGING ON
ILWU LOCAL #10 JURISDICTION AT PIER 92.”
The Employer filed an 8(b)(4)(D) charge against Local
10 on October 11. On October 16, Local 10 notified
Region 20 that it would not engage in picketing or simi-
lar conduct at pier 92 pending a resolution of the under-
lying jurisdictional dispute between the two unions. The
Employer started unloading the barge on October 22,
using its employees represented by the Operating Engi-
neers.
B. Work in Dispute
The parties stipulate that the disputed work is “the
movement of bulk aggregate rock and/or sand by bucket
loader from a barge located at Pier 92 in San Francisco,
California, to its first and final point of rest in the hopper
on the barge.”
C. Contentions of the Parties
The Employer stipulates that this 10(k) dispute is
properly before the Board for determination. On the
merits of the dispute, the Employer asserts that the fac-
tors of collective-bargaining agreements, employer pref-
erence, past practice, area practice, relative skills and
training, and economy and efficiency of operations favor
awarding the disputed work to its employees represented
by the Operating Engineers.
Local 10 also stipulates that this jurisdictional dispute
is properly before the Board for determination. On the
merits of the dispute, Local 10 contends that the work in
dispute should be awarded to ILWU-represented em-
ployees based on the factors of employer past practice
and area and industry practice.7
D. Applicability of the Statute
The Board may proceed with a determination of a dis-
pute under Section 10(k) of the Act only if there is rea-
sonable cause to believe that Section 8(b)(4)(D) has been
violated. This standard requires finding that there is rea-
sonable cause to believe that there are competing claims
to the disputed work, and that a party has used proscribed
means to enforce its claim to the work in dispute. Addi-
tionally, there must be a finding that the parties have not
agreed on a method for the voluntary adjustment of the
dispute. See, e.g., Operating Engineers Local 150 (R&D
Thiel), 345 NLRB 1137, 1139 (2005).
We find that these requirements have been met. The
parties stipulated that Local 3 and Local 10 both claim
the work in dispute. In addition, as stated above, on Sep-
tember 21, the day the barge arrived, Local 10 picketed
the Employer at pier 92 with signs reading: “CEMEX
AND LOCAL #3 OPERATING ENGINEERS ARE
7 Local 3 did not file a posthearing brief.
INFRINGING ON ILWU LOCAL #10 JURISDICTION
AT PIER 92.”
The parties stipulate and we find that
there is reasonable cause to believe that Local 10 used
proscribed means to enforce its claim to the disputed
work. See, e.g., Operating Engineers Local 150 (Royal
Components), 348 NLRB 1369, 1370 (2006). Finally,
the parties stipulated that there is no agreed-upon method
of resolving the dispute.
We therefore find that there is reasonable cause to be-
lieve that a violation of Section 8(b)(4)(D) has occurred
and that there exists no agreed-upon method for volun-
tary adjustment of the dispute within the meaning of Sec-
tion 10(k). Accordingly, we find that the dispute is prop-
erly before the Board for determination.
E. Merits of the Dispute
Section 10(k) requires the Board to make an affirma-
tive award of disputed work after considering various
factors. NLRB v. Electrical Workers Local 1212 (Co-
lumbia Broadcasting), 364 U.S. 573, 577 (1961). The
Board has held that its determination in a jurisdictional
dispute is an act of judgment based on common sense
and experience, reached by balancing the factors in-
volved in a particular case. Machinists Lodge 1743 (J. A.
Jones Construction), 135 NLRB 1402 (1962).
We have considered the following factors, which we
find relevant, and, for the reasons set forth more fully
below, we conclude that the Employer’s employees rep-
resented by the Operating Engineers are entitled to per-
form the work in dispute.
1. Certifications and collective-bargaining agreements
There is no evidence of any Board certifications con-
cerning the employees involved in this dispute. The par-
ties stipulated that the Employer is not failing to comply
with a Board order or certification determining the bar-
gaining representative for the employees performing the
work in dispute. Accordingly, we find that the factor of
certification does not favor awarding the work in dispute
to employees represented by either union.
The Employer does not have a collective-bargaining
agreement with the ILWU.8 It does have a collective-
bargaining agreement with the Operating Engineers.
That agreement covers all of its employees engaged in
producing concrete at the Employer’s pier 92 batch plant.
The agreement does not expressly and specifically refer
to the work in dispute. It does, however, refer to that
work in more general terms. The agreement requires the
8 Local 10 notes, and the Employer acknowledges, that the Employer
contracts with stevedoring companies to unload oceangoing vessels,
and that the employees of those companies are covered by a collective-
bargaining agreement between Local 10 and the Pacific Maritime As-
sociation. The Employer is not, however, bound to that agreement.
DECISIONS OF THE NATIONAL LABOR RELATIONS BOARD
164
Employer to recognize Local 3 “as the sole collective
bargaining representative of all Employees of the Em-
ployer performing work within the recognized jurisdic-
tion of [the Operating Engineers].” It has long been ac-
knowledged that the operation of heavy equipment is
within the recognized jurisdiction of the Operating Engi-
neers, see Operating Engineers Local 825 (Cruz Con-
tractors), 239 NLRB 490, 493 (1978), and it is equally
well established that front-end loaders are heavy equip-
ment, see, e.g., Desert Aggregates, 340 NLRB 289, 298
(2003); Laborers Local 76 (Carlson & Co.), 286 NLRB
698, 698 (1987). In addition, the Employer’s collective-
bargaining agreement with Local 3 includes the classifi-
cation “mechanical loader”; Local 3’s district representa-
tive testified that, although employees working in any of
the classifications set forth in the agreement are capable
of performing the disputed work, operation of the bucket
loader falls within the duties of the agreement’s “me-
chanical loader” classification. Pursuant to the agree-
ment, the Employer has assigned the operation of a
bucket loader to move materials at the plant to employ-
ees represented by the Operating Engineers. Based on the
foregoing, the factor of collective-bargaining agreements
favors awarding the work in dispute to employees repre-
sented by the Operating Engineers. See Longshoremen
ILA Local 3000 (Coastal Cargo), 289 NLRB 542, 544
fn. 9 (1988) (finding collective-bargaining agreement
factor favored awarding disputed work to employees
represented by the Teamsters, where employer’s agree-
ment with the Teamsters listed covered job classifica-
tions but did not describe the work performed by those
classifications, and the employer had no agreement with
the rival ILA); Longshoremen ILA Local 1242 (Depend-
able Distribution), 316 NLRB 1, 2 (1995) (finding col-
lective-bargaining agreement factor favored awarding
disputed work of unloading and warehousing cocoa
beans to employees represented by union that had
agreement with employer covering all warehouse em-
ployees, over workers represented by competing union
that had no agreement with employer).
2. Employer preference and past practice
The Employer does not employ ILWU-represented
employees and has never assigned any work to ILWU-
represented employees. The Employer has always used
employees represented by the Operating Engineers to
perform work related to the production of concrete, in-
cluding operating a bucket loader to move materials at
the plant. Nevertheless, the operation of a bucket loader
to unload a barge was performed for the first time after
the barge delivery arrived at pier 92 in September. Thus,
the Employer has no past practice of assigning the work
in dispute, and we find that the factor of past practice
does not favor an award of the disputed work to employ-
ees represented by either Union.
The Employer currently assigns the disputed work to
its own employees represented by the Operating Engi-
neers because it considers itself obligated by the collec-
tive-bargaining agreement to do so and because it be-
lieves that it is more efficient to assign the disputed work
to employees familiar with the overall operation. The
Employer prefers that the work in dispute continue to be
performed by employees represented by the Operating
Engineers. Thus, we find that the factor of employer
preference favors assigning the work to employees repre-
sented by Local 3.9
3. Industry and area practice
The Employer, the Operating Engineers, and the
ILWU each introduced evidence concerning the loading
and unloading of various bulk materials from vessels in
the San Francisco Bay area.10
Local 3 introduced evidence that employees repre-
sented by the Operating Engineers have loaded and
unloaded bulk materials—aggregate rock, sand, and
dredge spoils—from barges for other Bay area employ-
ers.
The Operating Engineers’ district representative
testified that workers represented by Local 3 have
unloaded asphalt aggregate from barges onto conveyor
belts that carry the material into asphalt production facili-
ties. Specifically, the district representative testified that
workers represented by the Operating Engineers at a fa-
cility located in Petaluma, California, have unloaded
asphalt aggregate from a barge using a front-end loader.
The ILWU contends that the sand and aggregate deliv-
ered by barge to the Employer at pier 92 is “revenue cargo,”
i.e., “cargo that someone has paid for and put on a vessel to
be shipped and received elsewhere.” Local 10 introduced
9 In its brief, the ILWU argues that the Employer’s stated preference
to assign the disputed work to employees represented by the Operating
Engineers is contradicted by the “admission” of Joe Sosteric, a manager
for the predecessor, RMC Pacific. An ILWU witness testified that,
when RMC Pacific was considering locating a batch plant adjacent to a
pier at the Port of San Francisco, Sosteric told him that the company
had no objection to assigning unloading of barge deliveries at the pier
to ILWU-represented workers. This testimony was admitted over the
Employer’s hearsay objection based on the ILWU counsel’s representa-
tion that it was not being offered for the truth of the matter asserted.
Contrary to her representation to the hearing officer, the ILWU in its
posthearing brief is plainly attempting to assert the truth of Sosteric’s
statement by characterizing it as an admission contrary to the Em-
ployer’s stated preference. In any event, there is no basis for finding
that Sosteric’s statement constitutes an admission by the Employer.
Sosteric was never an agent of the Employer; there is no evidence that
the Employer was even aware of the alleged statement, much less that
the Employer had authorized it, adopted it, or become in any way
bound by it.
10 The parties did not offer any separate evidence of industry prac-
tice. Indeed, they do not agree as to what the relevant industry is here.
LONGSHOREMEN ILWU LOCAL 10 (CEMEX CONSTRUCTION)
165
testimony that the unloading of “revenue cargo” at a com-
mercial dock, such as Pier 92, is work traditionally performed by
members of Local 10. Local 10 contends that employees repre-
sented by the Operating Engineers do not unload “revenue
cargo” at commercial docks, but only “construction materials”
at private company docks or at construction sites. Local
10 presented evidence that ILWU-represented employees
working for stevedoring companies in the San Francisco
Bay area have unloaded bulk cargo from vessels, includ-
ing by operating a self-unloading vessel’s conveyor sys-
tem to discharge sand and rock from the vessel’s holds,
and by unloading cement from the holds of oceangoing
vessels by means of a procedure that involves, at one
stage, the operation of bucket loaders.
We find that the foregoing evidence does not establish
a clear or consistent area or industry practice with regard
to the specific work in dispute. At best, the record shows
that employees represented by both unions have on occa-
sion performed work generally similar to the disputed
work. Accordingly, we find that the factor of area and
industry practice does not favor an award of the work in
dispute to employees represented by either Union.
4. Relative skills
There is no dispute that employees represented by Local 3 are
qualified to operate the bucket loader. Local 3 does not dispute
that workers represented by Local 10 have the skills to operate
the bucket loaders. The Employer does not dispute that some
workers represented by Local 10 have the requisite skills to
operate the bucket loader. We find that this factor does not favor
awarding the disputed work to employees represented by either
union.
5. Economy and efficiency of operations
The record shows that the Employer’s employees rep-
resented by the Operating Engineers interchangeably
perform all the functions necessary to carry out the Em-
ployer’s ready-mix concrete production operations at the
pier 92 batch plant. These functions include operating
bucket loaders to deliver raw materials to the conveyor
belt, controlling the conveyor belt system to coordinate
the movement and delivery of the proper materials in the
proper proportions to produce concrete to specification,
and performing routine maintenance on plant equipment.
The record further shows that the Employer has trained
its employees on the various jobs so they are familiar
with the entire operation. It regularly moves employees,
including the operator of the bucket loader, from one
function to another during the workday as needed. The
Employer also has moved the Local 3-represented em-
ployees to its other plants depending on production
needs. The record further indicates that the duration of
the barge unloading assignment varies daily from one to
several hours.
It is undisputed that ILWU-represented workers would
perform only the work of operating the bucket loader on
the barge and are not qualified to perform other work for
the Employer at the batch plant. Thus, when there was
no unloading to perform, the Employer could not assign
other work to ILWU-represented workers, who would
then be idle. Accordingly, we find that this factor
strongly favors awarding the disputed work to the Em-
ployer’s employees represented by the Operating Engi-
neers.11
Conclusion
After considering all the relevant factors, we conclude
that employees represented by International Union of
Operating Engineers, Local 3, AFL–CIO are entitled to
continue performing the work in dispute. We reach this
conclusion relying on the factors of collective-bargaining
agreements, employer preference, and economy and effi-
ciency of operations. In making this determination, we
award the work to employees represented by the Operat-
ing Engineers, not to that labor organization or to its
members. The determination is limited to the contro-
versy that gave rise to this proceeding.
DETERMINATION OF DISPUTE
The National Labor Relations Board makes the follow-
ing Determination of Dispute.
1. Employees of CEMEX Construction Materials, L.P.
represented by the International Union of Operating En-
gineers, Local 3, AFL–CIO are entitled to perform the
movement of bulk aggregate rock and/or sand by bucket
loader from a barge located at pier 92 in San Francisco,
California to its first and final point of rest in the hopper
on the barge.
2. International Longshore and Warehouse Union, Lo-
cal 10, AFL–CIO is not entitled by means proscribed by
Section 8(b)(4)(D) of the Act to force CEMEX Construc-
tion Materials, L.P. to assign the disputed work to work-
ers represented by it.
11 In arguing that the factor of economy and efficiency of operations
favors an award of the disputed work to employees represented by the
Operating Engineers, the Employer expressed a concern that Local 10 may not
have a sufficient number of qualified bucket-loader operators to ensure that, on any
given day, its hiring hall could supply a qualified operator to the Employer. Local
10 claims that it has enough workers at the hiring hall who possess all the requisite
skills, so that the Employer's operations would not be adversely affected by an
award of the disputed work to ILWU-represented employees. Because the
reasons described above lead us to find that this factor strongly favors
awarding the work to employees represented by Local 3, we find it
unnecessary to address whether the Employer’s concern is valid and
further bolsters that finding. Thus, we do not pass on whether the
ILWU’s hiring hall would have enough qualified bucket-loader opera-
tors to supply the Employer’s needs.

3. Within 14 days from this date, International Long-
shore and Warehouse Union, Local 10, AFL–CIO shall
notify the Regional Director for Region 20 in writing
whether it will refrain from forcing the Employer, by
means proscribed by Section 8(b)(4)(D), to assign the
disputed work in a manner inconsistent with this deter-
mination.
