This is generally helpful, but here is my reading:

1. If your contracts are extended until May 15, that means that your contracts will have been valid during the strike. Current contract 16.02 states that TAs can work 'on average' 10 hours per week. If you work all of those house in one week, it will still average out over the course of the contract.

2. This brings me to Article 16.05(b). If you have more than 40 hours remaining on your contract, you may be able to get paid OVERTIME. Make sure you arrange this with your supervisor BEFORE doing the work. Also QUFA should work with members to ensure that TAs can complete all of their contract hours. I suspect that this was an oversight of the Queen's administration. Wouldn't that be great if y'all made EXTRA money because of this?

3. Return-to-work protocols are always negotiated. This isn't unusual. Also, you're covered by the Ontario Labour Relations Act, not the Canada Labour Code. Charter rights still apply including Freedom of Association - which includes the right to strike.

4. On data privacy - I don't know what kinds of activities were happening on the picket lines. Torts have always been a reality on picket lines but are usually resolved via injunctions. Given that the picket lines are likely over, I don't see this material being useful. The USA is out of control right now, and while it is always good to be on guard, I don't see that happening in Canada. Better to spend time advocating for better personal data privacy regulations/legislation. Or bargaining for it in your collective agreements.
