- Employees at IT company Nutzwerk Ltd, in Leipzig, have to agree to be in a good mood as part of their employment contract.
Manager Thomas Kuwatsch said those who get up on the wrong side of the bed should stay at home and work out their grumpiness rather than come into work.
But he warned those taking too much time off for bad moods would face the sack.
"We made the ban on moaning and grumpiness at work official after one female employee refused to subscribe to the company's philosophy of always smiling," he said.
I'm going home.
