It’s always been a peeve of mine when a boss or supervisor claims, “We’re like family here at Acme Incorporated.” With one exception, I haven’t worked at any of these places, but that doesn’t prevent me from knowing the claim is a steaming-hot pile of garbage.
When everything is going well we’re all family. Work hard! Do it for your family! But that in no way prevents them from tossing you out with no notice when you’re inconvenient. Non-dysfunctional families don’t do this but a business absolutely will throw you out like yesterday’s garbage.
