if the proffessionals you work with don't model good behaviour, good manners, treat each other with respect how are the children expected to learn this behaviour. Examples of this are shouting at each other, not saying please and thank you, not making time to listen to each other or giving time for others to answer i am sure there are others but can't think at the moment. Your setting will have policies and procedures in place for you to voice your concerns try and have a look at these. If you can't then it is usually your manager you go to first unless they are the one you are complaining about then you go to whover is above them
