My best friend quit his job last week because of his toxic boss. Before he did he made a pros and cons list about the job, ripped it up, and hid it in the trash bin. He went out to lunch and never returned. An old co-worker called him yesterday to say the boss got everyone together and read the taped-together list that he wrote to the rest of the staff. She's apparently in shambles about him leaving. What causes people to act like this?
