The union filed a policy grievance alleging the employer failed to deduct union dues for apprentices.
The employer brought a preliminary motion to dismiss the grievance based on the doctrines of laches and abandonment, noting that apprentices had been excluded from the bargaining unit for approximately 50 years without union objection.
The arbitrator found that while the failure to deduct dues constituted a continuing grievance, the union's 50-year delay amounted to acquiescence.
Furthermore, the significant passage of time caused detriment to the employer, as it would be unable to proffer evidence or witnesses from historical bargaining sessions.
The preliminary motion was granted and the grievance was dismissed.
