Schedule
In the schedule, you add employees and assign their work days and hours. Each employee has access to their own schedule, and if you give them permissions, they can also access the schedules of other people.
The schedule checks that an employee does not have two shifts assigned at the same time and that they are not on vacation. It also counts the number of hours each employee works in a given month.
The schedule is available in the app, but it can also be synchronized in iCAL format with external calendar applications such as Google Calendar, Outlook, and Apple Calendar.
