In the business environment, as in life, you may like some people better than others. In your personal life, being nice to and doing favors for those with whom you get along makes perfect sense, but the rules are different at work, where you must treat employees equally and fairly. You may not want to give some employees as many perks, atta-boys or rewards as others – even if they are deserved – and you may not want to discipline an employee you truly like, but if you play favorites, your staff will notice. And it could hurt you and your practice.
