Well you have clearly missed the point of my comment.
Yes, it's "forced" on them, in the same way that many many other behavioural expectations are "forced" on a worker. They're "forced" not to abuse their co-workers. They're "forced" to treat their workplace with respect. They're "forced" to dress in a certain way.
That's called "having a job", and it's all stuff I've had to do, too, in every job I've ever had.
