The complainant, a structural steelfitter's helper, was assigned sweeping duties upon returning to work.
He objected to the assignment, considering it a constructive demotion, and was eventually discharged for refusing to sweep.
The union assisted him in filing a discharge grievance and attempted to negotiate his reinstatement, but the complainant refused to return if it meant sweeping.
The union membership subsequently voted against taking the grievance to arbitration.
The complainant alleged the union breached its duty of fair representation.
The Board dismissed the complaint, finding no evidence of arbitrary, discriminatory, or bad faith conduct by the union, which had reasonably concluded the employer was within its rights to assign the work.
