A friend of mine worked in a movie theater a few years ago and was wrongly accused by his manager of stealing those big cardboard cutout movie ads that sit in the lobby.
As a tremendous fuck-you, he called everyone that was meant to work on a Saturday night and offered, kindly, to switch shifts with him.
He never showed up, and neither did anyone else. Managers were scrambling trying to fill shifts and had to all come in at once to try and get everything done.
Just an idea, do with it what you will 😉
