Can I leave early if I already have my weekly hours?

That is up to your contract, collective agreement or works agreement, not the Working Time Act. With flexitime or trust-based hours it is often possible; with fixed hours it needs an agreement.

Does German law set a minimum working time per day?

No. Section 3 ArbZG only limits the day from above: 8 hours, up to 10 if 8 hours are not exceeded on average.

Do I get minus hours if my employer sends me home?

Usually you keep your pay without having to make up the time (default of acceptance, section 615 BGB). What applies to a time account depends on the agreement.

Leaving early today: when your week still adds up

In short

German working-time law only limits your day from above: 8 hours, at most 10. How long a day has to be at least, and whether you can leave early today, is up to your contract: fixed hours, flexitime, a time account or trust-based hours. If your model counts weekly hours, a long Monday can carry a short Friday. When in doubt, agree it first.

What the law covers, and what it does not

Ben works 39 hours a week at a planning office. On Monday and Tuesday he did ten hours each because a project had to be finished. On Friday he would like to leave at noon, it is his daughter’s birthday. Can he?

The German Working Time Act only helps halfway. Section 3 says: at most eight hours per working day, up to ten as an exception if eight hours per working day are not exceeded on average over six months or 24 weeks. So the law protects you from days that are too long. It has no minimum length for a day. That is in your contract, a collective agreement or a works agreement.

Four models, four answers

Fixed hoursYour employer decides when you work, within your contract, collective agreement and works agreement (section 106 Trade Regulation Act). Leaving early needs an agreement here, even if your week is already full.
Flexitime with core hoursYou are there during core hours; before and after, you plan yourself. Plus and minus run on an account, up to the agreed limits. Leaving at noon on Friday is often possible if core hours are over by then.
Time accountExtra hours are saved and balanced later. How much plus and minus is allowed and how you take time off is in the agreement.
Trust-based hoursYou decide when you work. But the agreed hours are still owed, and the Working Time Act still applies, apart from a few exceptions such as senior executives. This is where your own count helps most, so that “trust” does not mean nobody counts any more.

When your employer sends you home

A special case: you want to work, but there is nothing to do, and your manager sends you home early. Then you usually keep your pay without having to make up the hours. German civil law calls this default of acceptance (section 615 BGB). Whether minus hours may be booked to your account in that case depends on what was agreed about the account. Write such days down with a note: “Sent home at 2 pm, no stock.”

Think in weeks, not days

Many people assume every day has to meet its target, and a shorter day means “minus”. If your model counts weekly hours, that is skewed. A short day is then just part of the week, not a mistake.

Mika works part time, 25 hours a week, and picks up the child in the afternoon. Some Tuesdays it is six hours, Thursday only four. At the end of the week there are 25. That is neither minus nor plus. It is a week that adds up.

That is why Fieravend shows you the week next to the day, in a week strip at a glance. Whether you may leave early today is not something the app answers. It shows you the numbers, so you can ask well prepared.

How to talk about it

With numbers, not a feeling“I am already at 30 of 39 hours this week. Can I leave at 12 on Friday?” is easier to answer than “I have done loads this week.”
In good timeAsk on Wednesday, not on Friday at 11:55 am.
With the team in mindWho takes over what comes up on Friday afternoon?

Upper limits still apply

Flexible does not mean limitless. Even if you balance long days later, breaks still apply (more than six hours: 30 minutes, more than nine: 45 minutes) and so do eleven hours of rest between two working days. The finish-time calculator works out when you can finish under these rules. If a long day continues on the laptop in the evening, also read Back on the laptop in the evening.
