My question is; should I hire the qualified and bright business major, or the really hot college coed? (;
Firing should be quick and clean. Thank them, follow them to their desk, and escort them out the door. That way they can't talk to the other employees, or steal/break anything. Make sure you get any passwords to to the computer, and or company systems. Make sure with IT, they can't access anything from the outside/offsite.
As for hiring, hire the best looking business major! Think Slema Blair! She can look average, but then she can look hot!
