Dear Mr./Ms. Bossname,
I am resigning, with my last day of work being in two weeks’ time.
Due to increasing family obligations and a desire for work-life balance, I have accepted a position at a company that offers a flexible schedule.
I have enjoyed my time at the company, and especially appreciate your mentorship over the years.
I urge the company to consider being more flexible with work hours and location. I know that I’m not the only employee who is planning a move.
