Angry Manager
There’s nothing worse in the workplace than an obnoxious manager. That seems to be the case in this scenario because they left a horrible, passive-aggressive note. They write in a mean and sarcastic way that’s sure to infuriate all of their staff members. This must have raised tensions to the next level in the office.

The manager cruelly advises them to wear a sweatshirt instead of touching the heating system. It shouldn’t be too much to expect a little bit of warmth in the workplace. But the supervisor shows their true colors in true Scrooge fashion. Charles Dickens couldn’t have written a nastier character (via Reddit).
