Legal notes for this shift
Night premium
90 minutes of this shift fall in the night window (23:00–06:00). Under German law (§ 6 ArbZG) night work entitles the worker to a reasonable premium or compensatory time off.
Daily rest
After finishing at 04:00, an uninterrupted rest period of 11 hours is required (§ 5 ArbZG). The earliest permitted next start is 15:00.
Part-time
At 1,00 net decimal hours (01:00) this shift is under 6 hours and typically falls into part-time or mini-job territory.
Net Work Hours from 02:30 to 04:00 (after break)
As a work shift, 02:30–04:00 gives 01:00 net with a 30-minute break — that is 1.00 decimal hours for payroll.
Rest breaks are unpaid: a shift over 6 hours typically requires a 20–30 minute break that is deducted from paid time.

Calculating the Duration from 02:30 to 04:00
02:30 to 04:00 is 1.5 gross hours. Treated as a work shift, you subtract the unpaid break: a rest break of at least 20–30 minutes is standard — and legally required in many regions — once a shift passes 6 hours.
Legal & practical context for 02:30–04:00
This pattern covers night or overnight work. Under most labour standards — the US FLSA or the UK Working Time Regulations — hours worked between roughly 11:00 PM and 6:00 AM can trigger night-shift differentials, premium pay or compensatory rest. Because overnight work carries health impacts, regulations mandate strict compliance with maximum shift lengths and, in the EU/UK, free health assessments for regular night workers.
