Just the bare facts

What is a strike mandate?

Strike mandates are received by holding strike votes and receiving the support of the majority of employees. Most collective agreements are settled without a strike or a lockout, even when a strike vote is held. The best way to avoid a work stoppage is to have a strong strike mandate – in other words, a strong, credible vote in favour of striking. A strong strike mandate puts pressure on the employer and would give us the best chance of getting a deal that works for us.
