If you can't see or access the Contracts or Absences section of the staff profile for other staff, it's likely you don't have the right role.
Users need the HR role to be able to access these areas.
The ScholarPack Users report (Reporting > Reports > Staff > ScholarPack Users) displays the assigned roles for each user - those with the Sysadmin and Admin Role can assign the HR role (or other roles) as required.
