This site is devoted to stylists, salon owners, and salon industry professionals. Click the banner above Salon management should be run like any other business. It is not.
Business is business.
Have a 3 strike rule with employees or renters. In the long run you will benefit for being known as a good business person. You run the salon, don't let the salon run you. Have each employee or renter sign it. There are no mis- understandings this way.
