This guy is a captain in the Army reserves, and took a job working nights while he was finishing his master’s degree. I graduated with my masters in 2018 but job market for my field in my area was hard for a while. All of his managers liked him, he got the job done well, and had a good relationship with the owner of the company. Then they brought a new manager on, and while things were fine at first, they quickly started to go downhill. Soon after, as I’m still working on the on-boarding process for the new company, he becomes enraged that a garbage can is dirty.
