It’s usually easier to find people who already think like you than to change the minds of people who don’t.
Not a good fit within the company culture? Are people always staying late and do they expect the same of you, while you want to enjoy your time off?
Is a corporate reorganization threatening to give you new responsibilities you don’t want?
You could lobby and use your political skills to try to obtain favorable treatment. You could try to convince others not to work overtime. You could try to postpone the reorganization.
Or you could just find a job elsewhere. You could work in an organization that respects its employees’ personal lives and that gives them a say when reorganizing.
Follow the path of least resistance unless there is a compelling reason not to.
