I am ready to agree with you if you’re not being hypocritical here. Surely you’re doing only the best work for your employer, and spending your own unpaid leisure and sleep time on honing your non-marketable but company-demanded skills, undergoing psychotherapy to get along better with your manager, and thinking of all the opportunities to save your employer more money.

It would be a shame though if you demanded unpaid work from others, but didn’t live by the same rule yourself.
