question 87
why should managers know how to do the work of the workers they supervise?
to have realistic expectations for workers
to coordinate employees efforts
to create a team spirit among employees
to establish a chain of command

Explanation:

Managers knowing their team's work helps set feasible goals, as they understand task complexities and time/skill requirements.
