Bargaining Unit Determinations
Section 1210
Section 1210.37Â Bargaining
Unit Determinations
a)Â Â Â Â Â Â Â Â In determining the appropriateness of a unit for purposes of
collective bargaining, the Administrative Law Judge and/or the Board shall
consider all relevant factors, including, but not limited to, such factors as
historical pattern of recognition; community of interest, including employee
skills and functions; degree of functional integration; interchangeability and
contact among employees; fragmentation of employee groups; common supervision,
wages, hours and other working conditions of the employees involved; and the
desires of the employees. If the employer alleges that the petitioned for unit
is not appropriate, it shall submit a detailed statement explaining why the
unit is not appropriate. The Administrative Law Judge may determine a unit
other than the one petitioned for is an appropriate unit. The employer or
union must inform the Administrative Law Judge whether it is willing to proceed
to an election or a determination of majority status through the Board's card
check procedures in a unit other than one petitioned for.
b)Â Â Â Â Â Â Â Â In describing the unit found appropriate for purposes of
collective bargaining, the Board may, at the parties' request, describe the
unit in job function terms rather than by job titles. Such unit descriptions
may also include those currently existing job titles that perform the job
functions.
c)Â Â Â Â Â Â Â Â A bargaining unit described as consisting of particular job
titles shall also include any job titles later created that are successor job
titles to the currently existing job titles or perform the same or
substantially similar job functions as the currently existing job titles.
