I don’t know if they’ll retaliate. I would prepare for that, though. Whatever you do, do not give them more ability to contact you. Try to keep records and keep it professional with Ann until you are out of the position. Once you are in the new job, it will be easier to distance yourself from them. And if Ann starts shit after you have started, it will be easier for you to point her out as the instigator.
The situation sucks, and I hope you have a better and easier time going forward. But it sounds like Ned and Ann are predators, and should be outed as such.
This seems like an issue with accepting the current economic system as the only system or leading to some neo-feudalism.
We could restructure society and the economy so that the “debts of previous generations” weren’t such a fucking weight.
