You get what you tolerate

If you tolerate disrespect, you will get more of it.

If you tolerate tardiness, don’t expect punctuality.

Teams with high bars only have those high bars because key members of the team have very little patience for behavior that doesn’t reflect the best in people. If you don’t want bad behavior, be explicit about not tolerating it.

PS: Of course, you stand on solid ground only if you aren’t guilty of the behavior yourself.
