Not in the conventional sense of someone who manages their day-to-day performance, conducts appraisals and so on.
But any self-managed team will have issues with parts of the organisation that go beyond their control.
It’s management’s job to act on the system. So we need managers to be solving the problems that interfere with any team’s ability to do their work.
Tradesmen will have issues with materials; call-centre workers will have issues with IT; police officers will have issues with social services.
When managers take responsibility for these things they are working to the same end as their teams, it changes the relationship between managers and workers.
