Yeah, supporting anecdote: only thing I got for trying to negociate my salary and benefits last time I tried, was my contract started over a month later so I technically lost that much pay, with zero changes to my contract. It just doesn't feel worth trying. Sure, you can blame me for poor negotiation skills maybe, or for not walking away from this job but contrast that to my partner's salary doubling without having to even ask... So it deeply irritates me when people say women don't get things because they don't ask. It is just a catch 22 situation.
