Speaking to my time in the service sector, I had a boss at one job and a coworker who ran a team at another who both suffered from the same affliction - their teams failed because the bosses couldn't let go. As leaders they were too hands on and refused to not be the loudest voice in the room. Instead of delegating or putting in human hours, they pushed themselves harder and refused to listen to feedback.
This resulted in extremely high turn over, resources lost in continuous recruitment cycles (for my unit as well), and an overall bad vibe for the team. Most importantly, their behavior had a direct impact on customer experience - when the leader was stressed, the staff was stressed, this hurt performance and trickled down into the interactions with customers. Leaders blamed poor performance on the staffs' "incompetence," not the yelling or the curt responses to very normal questions during training or one sided conversations.
Do you think this is a problem in all sectors? Is it something innately human? Is it worse for certain employment sectors?
