"A beauty offer" is formed mostly by small salons, sometimes chains, so corporate culture is not a matter of discussion, but the relatioship between heads and specialists is.
One of the major problems in beauty-related dealings is cronyism, when there's no distinguish between friendship and work. It puts the whole firm at risk, carrying lack of discipline and a decline in quality.
Usually, it is in directors' responsibilities and power to establish the way employees interact with each other. It is not a formal rule, those in charge should pay close attention, guess moods, most importantly, give their own positive example. Running a salon, your relationships with the team are always in full view of everybody. Your manner is a silent pattern, and the smaller your team is, the greater such influence will be.
Finding the balance between strict corporate discipline and fellowship rules of conduct and accepting it as a norm is as necessary as observing other regulations in the sphere. You are in charge - make sure it's done. There's nothing criminal in being a friendly and easy-going boss if some boundaries are respected. The reasonable scale of politeness and understanding at work should be unquestionable.
Do not assume that harshness brings a lot of good either. It may simply turn the employees on you. Tore up boss is a tempting topic for rumors which may consequently affect your reputation and services quality.
To work out a rational behavior, try to convey the right message to the team: the director is in charge of the whole business, and being an owner doesn't make him free from completing the plan, taking care of every little thing, be it technical, economic or legal matter. That's why informality at work is so dangerous for salon's functioning.
