Dear Mr./Ms. Bossname,
I am writing to affirm my resignation effective two weeks from yesterday, and clarify that after reviewing the company’s HR procedures manual, I am indeed entitled to my vacation leave and accrued sick pay.
I gave you two weeks’ notice, which means I am willing to work until May 24. I don’t know why you insist that “two weeks” should be calculated as the end of the current pay period and one complete, additional pay cycle. That’s not what the manual says, and more importantly, that’s not what the law says in our state. In fact, two weeks is considered a courtesy; it is not required in any professional setting.
I know that my leaving puts you in a bind, but I urge you not to take it out on me with petty retaliations that will only fail to hold up to legal challenges.
