Outside of your job duties you have to do what you can to help maintain the smooth running of the facility as well as ensure patient and staff satisfaction, making sure your boss never has to step in or even think about you. Your job is NOT to judge anyone or express opinions about sex, religion, politics, or make ANYONE feel uncomfortable. This interferes with the normal functioning of the system and like a bad part in machine you will be ousted.
People may call it being PC, touchy-feely and a kiss-up, but if you're not sincerely concerned about the staff, customers and your boss, why should they care about you?
It's really as easy as putting others before you in conversation, taking nothing personally, taking interest in how everyone is doing and doing what you can to bring them up. 90% of the time all you have to do is drop the ego for a second, listen and reiterate what they said before you speak.
Its like doctors who complain about nurses. Most of the time docs think they're better than the staff. That's childish. If you recognize everyone is important, make them feel so and value their input things will run much more smoothly, everyone will be happier, the patients will get better care and your boss will get less headaches.
