 At work we have a kitchenette and at the end of the day, my coworkers leave their dishes/mugs filled with oatmeal and other things left to soak. We even have a sign that states “Do not leave personal belongings in the kitchenette. We are not responsible for lost items”. I stay at work pretty late so I see the night janitor come in and clean. I noticed that he goes out of his way to wash the dishes and mugs, which isn’t a part of his job (our company only contracts them to do floors and trash so it’s our responsibility to clean up after ourselves). My coworkers must have noticed too because they have since stopped doing their own dishes and has been leaving piles in the sink knowing that they will be magically washed and dried in the morning. They even make comments about the “Mexican sucker” that’s cleaning for them. This has been on going for a few weeks now and my coworkers even have the audacity to complain about water spots on their mugs. So throughout the day when I find myself alone in the kitchenette, I take an item or two and toss them out in the building hallway trash so it can’t be found. We work in a building where we share office space with other businesses and there’s no cameras so I haven’t been caught yet. A coworker asked our manager about their items being taken, but my manager just reiterated the policy. I guess I am being petty, but my coworkers are trash and I don’t feel bad.
