Shabbat & Early Friday Finishes: A Guide for Employers

Understanding Jewish Sabbath (Shabbat) requirements, Friday sunsets, and flexible working adjustments.

What is Shabbat?

Shabbat (the Sabbath) is the most significant manufacturing day in the Jewish calendar. It is a day of rest where work is strictly forbidden for observant Jews.

Crucial Timing: Shabbat does not begin at midnight. It begins at sunset on Friday and ends at nightfall on Saturday.

The “Winter Problem”

In the summer, sunset in the UK can be as late as 9:00 PM. But in winter, sunset can be as early as 3:45 PM.

This creates a major conflict for the standard “9-to-5” workday. An observant Jewish employee strictly cannot work once Shabbat begins. They need to be home, with candles lit, before sunset. This means they often need to leave the office by 1:30 PM - 2:30 PM on Fridays in winter to travel home in time.

Reasonable Adjustments for Shabbat

Refusing to allow a Jewish employee to leave early on Fridays is almost certainly indirect discrimination, unless you can prove it is impossible for the business to function.

Common Solutions

Compressed Hours (Annualised):
- The employee works longer hours Mon-Thu to “make up” the time lost on Friday afternoon.
Seasonal Shifts:
- The adjustment is only needed from October to March. In summer, they work normal Friday hours.
Lunch Break Swaps:
- Skipping lunch breaks Mon-Thu to accrue time off for Friday.

Can you deduct pay?

If the employee cannot make up the hours (e.g., the office closes at 6 PM Mon-Thu so they can’t stay late), then reducing their pay pro-rata for the reduced hours is a lawful option. However, most employers prefer to find a way to keep them full-time by allowing flexible start times (e.g., starting at 8 AM).

What about Saturday work?

If your business operates on Saturdays (retail, hospitality), observant Jewish staff generally cannot work at all on Saturdays.

Unlike some Christian beliefs where Sunday work is disliked but possible, for Orthodox Jews, Shabbat rules are strict prohibitions against using technology, writing, travel, or handling money.

Verdict: Asking an Orthodox Jew to work Saturday shifts is rarely reasonable. You should almost always look to roster them on Sundays or other days instead.
