I'm going to let a new employee go
Why would you let them go?
Because he's not as good as Bob, another coworker
It's fine to fire someone if they aren't doing their job right. You should fire the new employee if they aren't as good as Bob, a model employee.
Fuck him, I'll fire the employee anyways. A stupid cunt like him doesn't deserve to work here.
There's no need to be hostile towards him, you should just fire him and move on with your life.
