I recently got told to check out
The One Minute Manager and was surprised to discover I've already been trying to do the things listed within. The principles are simple: Let people know what you expect of them, Let people know when they do something right, let people know when they do something wrong... and do it all within one minute.
I do stray from the book in one aspect, though. The One Minute Manager recommends that your reprimands be personal, stating how the coworker makes you feel when they fail to perform adequately. I think that this can seem confrontational. So when I have an issue with a particular behavior, I bring it up in shift meeting as a disembodied action... unattached to the person who performed it. This allows me to address the issue, rather than the person. I feel this empowers people. It makes them recognize they are part of a team, and the behavior is universally expected rather than singling them out as a bad seed.
What sometimes happens after I address an issue is that someone thinks it is cute and clever to re-personalize the issue. They will publicly fess up to the behavior and say, "That was me." This wouldn't be trouble if that was the end of it, but what invariably follows is a long list of excuses and partial justifications for a behavior I have just publicly stated is not acceptable. This turns my impersonal and simple one-minute goal session into a public and personal reprimand.
This does not make me happy, and more often than not, makes me feel as if the coworker is directly inhibiting my ability to do my job effectively. By subverting my attempts to cleanly address what is expected of the service staff, this person has made my work harder, aggrevated the relationship between management and staff, and turned policy into he-said/she-said. I sometimes wonder if you can see the hair on the back of my neck standing up during these times. I sometimes want to hiss like a snake and raise my hands like cat claws.
I want to be a good manager, but the restaurant industry is hell on me, sometimes.
