It's insane when your boss demands your effort though you've already called it quit.
OP finds themselves in a situation where they provided a two-week notice, with a specified last working day of February 11th. However, despite the clear communication, OP's boss included them in the schedule for the following week and expected them to continue working. OP, having expressed the need for a break to address their physical and mental health, rightfully declined to work beyond their agreed-upon last day.
OP's boss, rather than acknowledging the agreed-upon notice period, assumed that OP would be available to work during the following week and labeled them as "selfish" and "inconsiderate" in an email to everyone. However, OP asserts their need for a break due to the excessive working hours and the toll it has taken on their personal life and health.
Let's see whether OP is TA or not.
