The pressure isn't internal, it comes from a boss pointing to one worker's schedule to get leverage over another. I think it's responsible to keep such ammunition out of the hands of bosses.
I agree, but a complete solution is often out of reach.
Also, many bosses aren't crazed gunmen, but they're still uncareful about how they communicate and wield their power. By being careful as a worker, you can reduce the accidental harm these bosses do.
