A similar situation happened at a privately owned prototype fabrication shop where I used to work. This was the kind of place that would treat you very well if you worked hard and did your job well. We even had unlimited overtime ( up to 24 hrs. per day!) anytime we wanted it and for any reason.
Business got slow, so they laid off a few guys that weren't very productive. They kept them around when things were busy, but it was their way of letting them go without firing them and used the slow time as a good excuse.
Anyway, the general rule was that the shop foreman had to make sure that none of the company tools were hidden in somone's box, however he wasn't there that particular day, They asked everyone to be patient, come back the next day to get their stuff, and everyone was OK with it except 1 guy. When he couldn't have his stuff right then and now, he called the Sheriff dept. who came and talked to the company owner/president. The employee ended up getting his box and tools, but that wasn't the end of it.
Everyone else laid off pretty much figured out that they weren't coming back except for, you know who. One day, one of the managers said that the guy that called the police on the owner had just called the shop. After the whole police episode, he actually assumed that they were now going to let him waltz in and start working there again. Needless to say, that was never going to happen.
