Yes, you can. First, you need to go to Settings –>Working Time/Reminders, and check the box “Enable Weekly Hours Pattern”. You will notice a new table appears where you can specify a number of hours per day. You can leave this set at the standard working week for the company. Click “Save”, and then return to your employee details page. You will now see an option “Set Employee Specific Weekly Hours Pattern”. Select this, and you will be able to define the number of hours this employee is expected to work for each day.
