We had a big project that needed to be shipped out on Friday, which was about impossible, and my boss was upset that we only did 8 hours on Tuesday. On Wednesday, he “asked” if everyone can do overtime and I told him that I couldn't due to”prior commitments,” and he swapped me with another worker who had never done my job before simply because he needed somebody “committed to overtime.” It sucks for my coworkers because they will be under pressure and impossible deadline, but I've had the biggest smile on my face knowing I got to him. I took Friday off because of the weather so I don't know how it went but I am looking for new jobs just in case.
