None in 3 years running. I'm doing my financial projections well. There could be some drastic cuts during the rest of this year, but absolutely everyone in the company is aware of that. We have 3 games due release pretty soon, and if only one is even moderately successful, I'll keep everyone running by me.
I came close to firing one, but we've managed to find a consensus and we drastically reassesed him and reassigned his responsibilities within the projects/company. It was a good decision - he's probably the most productive person on the team now.
