What are the strangest company rules you have ever seen?

I have personally seen the most wonderful company regulations and experienced them personally. All employees in the company from top to bottom must put down their jobs and take part in voluntary labor every Saturday. This labor is nothing more than weeding the factory and digging some sewers. The key is to ask them to drop all their work. The sales department also laid down all the work, and all the employees had to take part in the labor on that day. In this regard, the factory is euphemistically called to adhere to the labor tradition, but personally it is very incomprehensible.
