Industrial companies with continuous production need to manage shifts. Portuguese law has specific rules and attendance management becomes more complex: there is no fixed schedule — each week can be different. This article covers the essentials for managing shifts with fewer headaches.

Legal rules for shift work

• Night work (10pm–7am): minimum 25% premium on the hourly rate.
• Sunday work: 100% premium or compensatory rest. To understand the detailed calculations, see how to calculate overtime in Portugal.
• Rest between shifts: minimum 11 hours between the end of one shift and the start of the next. Violating this interval is a serious administrative offence.
• Schedule communication: the employee must know their shift with reasonable advance notice (minimum 1 week).

Most common shift models

• 2 fixed shifts: Team A always on mornings. Team B always on afternoons. Simpler to manage but some are always on the less preferred shift.
• 2 weekly rotating shifts: Week 1 — A mornings, B afternoons. Week 2 — A afternoons, B mornings. Fairer.
• 3 rotating shifts (continuous production): 3 teams rotating, each 8h. More complex, especially on weekends and public holidays.
• 4 teams (24/7 coverage): each team works 3 to 4 consecutive days then rests.

Challenges of attendance management in shift work

• Variable reference schedule: the system needs to know which shift each person is on for each specific day.
• Shift transition: clocking out at 6:45am on a night shift (10pm–6am) is not leaving early — the system must interpret this correctly.
• Overtime for cover: the system must distinguish between the normal shift and hours beyond it.
• Public holidays and shifts: if a holiday falls on a scheduled day, the record must be accurate to calculate the compensation due. To learn how to export this data to your accountant, read how to export time tracking data for payroll
