There are two types of managers in Clockify:
- Project manager: can view all tracked time on their projects, and edit everything on their projects (eg. set estimates, add tasks, manage project access, etc)
- Team manager : can view all tracked time of their team members (can't edit or delete time) and approve their submitted timesheets
You can give project manager role to someone by opening some project, going to Access tab, and clicking on three dots next to someone and choosing "Give manager rights".
Team manager role, on the other hand, is Enterprise feature and is currently in development.
