Doesn't help when you have notice period of 2 months
So cut some slack, put in the hours contractually necessary, but don't break your neck being at work 9AM sharp, meeting arbitrary deadlines set by management, or attending the meetings you could have just set to "tentative, but I'll probably pass, thanks".
1. Seems like it might be criminal to walk off the job if you're a surgeon in the middle of a operation, firefighter at a fire, etc.
2. Otherwise, it seems possible that you could be sued by your employer for walking off the job but criminal, probably not.
3. If my employer tried to physically prevent me from leaving work, I'd call the police immediately.
