In a theme park management game (might have been 'Theme Park') there was a negotiation mini-game for agreeing wages/supplier prices where you gradually reach out to shake each others hands. Give too much and you pay over the odds, give too little and the deal breaks down entirely.
You could include something similar for your hiring process perhaps.
PS - It was Theme Park. See the 2nd screenshot on this page (or maybe it's the 4th screenshot really given it's from the DS): http://www.gamingsteve.com/blab/index.php?topic=7952.0)
