my experience with labour relations tends to bear out that even good companies make bad decisions time to time, and very rarely is the relationship of the worker/employer beyond repair.
someone higher up in the company probably got wind of what was going on , or, after speaking with WCB they realized how badly they goofed and wanted to make you whole. I would give them that chance unless you genuinely don't trust them any more, which I wouldn't blame you for.
