Re: And this, kids,
Being of a not-litigious nature, I would have done ... nothing. Once the constructive dismissal has commenced, plans for new employment would be made, and the only remaining question is timing. Will they dismiss me first, or will I give notice first? Probably they will dismiss me first, because if I haven't given my notice already then I have made it into a game.
I think the mention of the funeral and timing was not "oh the grief", but more an example of just how low-down the manager was. Sounds as low as they get.
