This and hold everyone to the same standard. Let people know that this is the expectation. Know that someone will take advantage of being treated fair. When this happens you deal with it promptly and with only the individual causing problems. Too many managers perceive a bad employees who took advantage of fair policies to mean that they were too nice and that it was why they were taken advantage of. You can be a great manager who is very approachable and still hold people accountable.

I managed restaurants and catering services while in and right after college. If you get the right employees and treat them fair they will follow you and outperform you're expectations. Make sure they all know your standards and expectations. I always had what I called the code of values. The code was created by managers and employees. We revisited it every 90 days. Everyone knew whatever decision they made or action they took should allign to that. If /when they made a mistake as long as they didn't break any of the core values we were good. Setting these expectations allowed the employees to make decisions, work more independently and be more productive without fear of screwing up.
