Everything you need to know about 4-day week jobs

A 9-day fortnight arrangement reduces standard working hours while preserving full pay — the exact structure varies by employer. Some companies fix the non-working day (commonly Friday), others let employees pick. Total weekly hours typically land between 30 and 36, depending on the specific variant. The companies on this page have all publicly documented their version of the schedule, so their listings show whether the reduced day is fixed, rotating, or flexible. Expand any listing to see the specifics.

Currently, software and technology companies dominate the 9-day fortnight listings, followed by consulting firms, product organisations, and an increasing number of professional services and healthcare employers. This page lists 719 open roles at 10+ companies including L3Harris Technologies, Stanley Consultants, and Dolby. The range is broadening each year as high-profile pilots publish results and competitive-hiring pressure pushes more sectors to adopt reduced schedules.

For the listings on this page, no — the employers have publicly committed to full pay under the 9-day fortnight arrangement. This is the defining criterion for inclusion on 4dayweek.io (with the explicit exception of part-time and pro-rata roles, which are clearly labelled). Pilot studies from the UK 4 Day Week Campaign, Iceland's trials, and individual company reports consistently show productivity held flat or improved under full-pay schedules.

The most successful approach is to propose a trial period with clear success metrics — what output you'll maintain, how you'll track it, and when you'll review. Reference the published pilot data: the UK 4-day-week trial saw 92% of participating companies continue post-trial, with flat or improved revenue. Pitch it as a productivity experiment, not a lifestyle perk. If your employer declines, every company listed on this page already operates on a 9-day fortnight — switching may be faster than convincing.

9 Day Fortnight is one of several reduced-hours patterns — others include compressed weeks (40 hours in 4 days), 9-day fortnights (one Friday off every other week), flexible-hours policies (total hours capped but schedule flexible), and summer-only reductions. The common thread on 4dayweek.io is that full pay is preserved. Different arrangements suit different industries — engineering teams often favour flexible or fortnight patterns, customer-facing teams gravitate toward fixed-day arrangements for coverage clarity.
