Discretionary work is under a “de-facto working time system,” so does time away from the seat need to be applied for?

You must apply for time away from work. Under the Occupational Health and Safety Act, companies are obliged to keep proper track of their employees' working hours.

When you take a break other than a lunch break in TeamSpirit, press the ‘Out button’ and when you return, press the ‘In button’ or later use the ‘Attendance Related Request’ to ‘Change Break Time’.
