In one sense a manager is paid to do the job and act and behave in such a way that goes with the job and company policies. What the job is and which behaviors are required should be very clear.
A person considering a job as a manager then needs to assess his/her own personality, preferences and values and as if they want to do the job as required. If not look elsewhere.
A manager and his/her manager need to have conversations to ensure that there is a match between the required behaviors and what the manager wants to do. If there is a mismatch, then that will impact job performance and they need to handle that and maybe consider separation from that particular job.
