You've heard about managing by walking around. How about managing by working around?
Managing by working around is a concept where you work around the needs of others when it comes to their work schedules and weaknesses to build your team into one that becomes like a machine.
Too often, managers will work on trying to fix people's weaknesses; they try to fix people instead of focusing on their strong attributes.
Many employers will also piss and moan about someone needing time off, a flexible schedule, or consecutive days off rather than working with the talent that they have.
Manage by working around - you'll have a healthier, meatier staff and people that will always put forth their best.
