Great game but there are quite a few annoying bugs. After some time my workers stopped working (according to the info panel they were "waiting) and I had to fire them and hire new ones to restart the production. It also happened that a red face appeared on top of other workers (were they unhappy?!) and I could not even select them (I had to fire them from the personnel screen).
This is not a bug. They go on strike when you haven´t build enough break rooms.
The red face means the worker is on strike because in the moment when he
wanted to go to a break room both places were already in use or reserved for some other worker on the way. - If a worker is on strike you cant move him. A strike takes always 5 hours. - "Waiting" means you have the Anti-Strike Upgrade and the worker is waiting for a break room place instead of going on strike. Hint: Have always at least two break rooms when you have more workers.
