This may be a strange question but I haven't been able to find any advice or help on the topic through my searches. I have 3 teams of about 12 employees with recently promoted managers that are all not performing very well. One of my thoughts on their poor performance is that these teams previously had 3 experienced managers who were some of the best, so they were promoted. The teams haven't changed in any way other than a new manager was promoted to lead them. Now I'm feeling like these teams are rebelling against their new managers and maybe it would be best to rearrange the teams and taking 4 people from each team to create a new team. I don't want to do this as I know it's disruptive, but I feel like it might be the best choice I have. Any thoughts comments or suggestions on the topic would be greatly appreciated!
