People management is what most pharmacy managers get very wrong. I disagree with the above response(s) that managers should be promoted from within. That causes all kinds of problems with having to lead your former friends/coworkers. I've had some pretty terrible bosses that were great in their former roles. Take a course at your community college if your hospital doesn't offer something. Read a book. Don't underestimate how well a well timed compliment will pay off. You can catch your reports doing something wrong whenever you want. Expend a little effort and catch them doing something right.
I always considered my job managing operations as a buffer for my boss to not be involved in the day to day running of the pharmacy. Never tell your reports "We're doing this because the director said we're doing this." Have your disagreements with leadership in private.
