Severance Day
I worked at a small, privately owned chain of stores. The owner decided to buy a factory that made products for his stores which his wife now ran. After a few years, they only wanted to manufacture and leave the retail side. If they had closed, they would have had to pay some staff severance packages costing a fair amount of money.
They decided to consolidate the bookkeepers to the manufacturing site, and the stores stopped paying the manufacturing company. After a year of that, they went to the courts and declared the stores bankrupt as they owed the manufacturing company a significant amount. Some of the staff had worked there for more than 15 years and found out they had been disowned with no severance.
The owners were real jerks. They could have foregone a single luxury vacation and given those staff what they morally owed them.
