Last Updated:
CUPE Local 957 (technologists, ~2,700 members) and CUPE Local 1500 (skilled trades, ~6,200) will begin an overtime-only, indefinite strike at 00:01 on 14 May 2026 after more than two years of stalled bargaining. The Administrative Labour Tribunal approved the essential-services plan, so regular shifts continue and overtime will be worked only for emergencies; core issues include outsourcing and workforce flexibility.
