Emotional Work (Unpaid Hours)

I don't like to check my work email because when my boss or co-worker know that I've read the work email, they will start rattling off about work. Work is endless and forever urgent, given our work nature is 24-7 operationally hectic, there must be some form of a balance, right?

10 plus at night still Whatapp me about work?

I should be winding down for bed right?
