Co-workers can be granted different access rights. The access rights determine what co-workers can see and edit in Moment.
Go to Co-workers > Co-worker > Settings > Access. A regular co-worker should be granted the top three rights. Note that an administrator must be granted all access rights.
There also exists a new role based access control, where a co-worker can have their access from a role.
It is also possible to test what pages a user can see using the Test access button. This works for both the old and new access control systems.
