§ 5341. Trades and crafts (a) The pay of employees excepted from chapter 51 of this title by section 5102 (c) (7) of this title shall be fixed and adjusted from time to time as nearly as is consistent with the public interest in accordance with prevailing rates. (b) When the Civil Service Commission concurs in a finding by the employing agency that in a given area the number of employees to whom this section applies is so few as to make prevailing rate determinations impracticable, these employees are subject to the provisions of subchapter III of this chapter and chapter 51 of this title which are applicable to positions of equivalent difficulty or responsibility.
