I’m a (sort-of) contractor. My rates and selection of projects strongly takes the team dynamic at the clients place into account. Sure, I do have a rate that I aim for, but as long as a certain minimum is met, I’m likely to choose a place with a sane team and healthy social interactions over a dysfunctional hell hole. And places that pay everyone a reasonable wage at least tend to have that more often than other places.

This approach has shown to substantially improve my quality of life.
