Thank you so much for replying. My question is that Do I need to give the manager a specific permission to be able to approve time off and team members' timesheets.  In other words, if Employee "X" has the permission of "worker" and has been assigned as a manager of a group (He is not a member of that group) Does he need a custom permission  instead of worker to grand the access to timesheets and PTO requests of the team he manage?
