You have to lay it out on the line. If you are in a position of a leader, you owe it to everyone to lay out the rules. If you are one of the people who report to the same person as the people you have a problem with, take your concerns to them in an organized manner.
Some key things to remember in management are;
Follow the chain of command, ALWAYS!
Remember you have a problem with the behavior, not the person(s).
If you go to someone with a problem, make sure you also have a solution or even a few options.
You can either progress up by standing on the people you had to trample to get your way, or you can have them hold you up as a group...the latter is easier.
