You may think you’ve had some terrible bosses, but you’ve probably never encountered one as bad as the one who just wrote to Alison Green’s “Ask A Manager” advice website.

The manager in question oversees a customer support team at an unidentified company. One of his employees was a young woman who asked if she could come to work two hours later than her scheduled start time one day because she wanted to attend her college graduation.

According to the manager, this woman was one of his best workers and was his “go-to” person for working weekends and holidays. Additionally, she had to overcome a lot to graduate from college — as the manager writes, “she was raised in a few dozen different foster homes and has no living family” and “was homeless for a bit after she turned 18.”

Despite all this, the manager refused to let her come in two hours later.

“I told this team member that she could not start two hours late and that she would have to skip the ceremony,” the manager writes. “An hour later, she handed me her work ID and a list of all the times she had worked late/come in early/worked overtime for each and every one of her coworkers. Then she quit on the spot.”

As you can imagine, Green was not at all kind to the manager in her response.

“If anything, you should consider reaching out to her, apologizing for how you handled the situation, and offering her the job back if she wants it,” Green writes. “I’m not usually a fan of people quitting on the spot, but I applaud her for doing it in this case. She was raised in dozens of foster homes, used to be homeless, has no living family, and apparently managed to graduate from college all on her own. That’s amazing.”

There’s some good news here: Now that this employee has graduated college, she will likely be able to find a better job where she’s more appreciated.
