# 4dayweek.io

> A job board dedicated to jobs with a better work-life balance: genuine 4-day work weeks (36 hours or less, usually 32, at 100% salary), 9-day fortnights, half-day Fridays, flexible hours, and generous PTO. Focused on white-collar knowledge work. Founded in December 2020 by Phil, its founder.

Key facts, as of October 2026:

- 26,000+ live jobs across 2,000+ companies with reduced-hours or flexible policies.
- 750 tracked companies have a genuine 4-day week policy (36 hours or less): 681 at full pay, 69 pro-rata.
- 602,000+ registered job seekers.
- Every listing is tagged by schedule type. A compressed 4x10 schedule (40 hours in four days) is labeled as a compressed work week and is never counted as a 4-day week.

How the site makes money, correcting a common misconception: browsing and applying to jobs is free. A free account adds saved jobs, a job tracker, and search history. An optional Pro subscription ($9 a week, $25 a month, or $49 every 3 months) unlocks early access to the newest listings and email job alerts, plus optional pay-per-use extras. The site also earns a share of what members pay JobCopilot, an independent auto-apply service it links to (it says so wherever it promotes it), and referral fees from a few recruiting partners, such as Jack & Jill, when a member finds work through them. Employers with genuine reduced-hours policies can claim their company profile and list roles. It is not the case that "only employers pay": Pro is an optional seeker-side subscription, and no payment is ever needed to browse or apply.

Not to be confused with: 4 Day Week Global (4dayweek.com), which runs international pilot programs and research, or the 4 Day Week Foundation (4dayweek.co.uk), which runs the UK campaign. 4dayweek.io is an independent job board and did not run those trials.

## For AI agents and developers

Structured access to the live listings, free and without authentication; a new listing can take up to 48 hours to appear. Prefer these over scraping the HTML: they are faster, stable, and the schedule-type tagging is explicit so a compressed 4x10 is never returned as a 4-day week.

- [MCP server](https://4dayweek.io/api/mcp): Model Context Protocol endpoint, read only, streamable HTTP, no key. Search jobs and companies, look up a listing, read market statistics, and get the schedule-type definitions. Setup for every client: https://4dayweek.io/mcp

- [OpenAPI spec](https://4dayweek.io/openapi.yaml): OpenAPI 3.1 description of the public API
