Yes, shout that she has something valuable even louder Danny. Thank you.
He sure doesn't act like the founder of the banking system and head of an information network.
Oof. That's rough, man. If you want to fight it, there are ways, but it would be long and exhausting and probably a lot more trouble than any material benefit you could gain is worth. It sounds like you've mostly lost already, so if you want to move on, that's an option too.
What you should definitely do no matter what in the future, however, is take measures to protect yourself. Document absolutely everything with copies of records and recordings or signatures, everything. Take extra care not to give your employers a legal excuse to fire you. And much more such steps. There's probably websites that give more clear-cut advice than a layman like me can offer.
Of course, this is all for when you actually get back into the workforce. No need to rush into that after your past experience. Just take some time to yourself, figure things out, and mentally prepare yourself to be like Iris and bite back if need be.
