I've been working at this company for over 6 years and for those 6 years, my boss has been an absolute bully. He micro-manages everything I do, dumps so much work on me, and then criticizes everything that I do. He literally yells all the time and bangs on his desk. When he wants something done instantly, he would put a lot of intense pressure on me to the point where I feel like I'm about to have a heart attack. There have been several complaints about him from my colleagues and former colleagues, but no one does anything and he just gets worse. These past couple of weeks have been particularly bad where he's been dumping so much work on me that I've been working 12 hours a day straight with no lunch break. And the next day, he complains about the work I did and screams at me because there were other minor work that I was unable to complete due to the heavy workload.
I finally got fed up and decided to just quit. I have enough savings to live on for the next several years so I decided not to become a slave anymore. So I tried to resign today and in order to not end on bad terms, I tried giving two weeks notice and said that I have a very important family obligation that came up that will require me to be out of work for an extended period of time and I can no longer continue with the job.
My boss was stunned and said that I'm a very valued employee (which was shocking to hear after the way he always treated me) and he begged me to not be hasty and resign. He told me to take a leave of absence for as long as I want (even if it means several months) and start the leave anytime I want and I don't ever have to come back if I can't.
Why did my boss do this? How is this benefiting him? Any catch I should be aware of?
