I agree. Eg suppose you try to negotiate for a raise with your employer and they refuse to play along. What are you gonna do?

Probably better results to spend all your effort cultivating alternative options- who else would give you a job? How much would they pay you?

It's trickier if your visa is tied to your employer. Stating the obvious: that's not a great position to be in if it makes it much harder for you to switch jobs.

edit: it might also be useful to read about negotiation

e.g. the book "getting to yes"
