The four-day work week is no longer a management utopia: hundreds of companies across Europe and North America have adopted it, with often surprising results. But this new working pattern raises a practical question for HR teams and event planners: how do you schedule seminars when Friday no longer exists?

The 4-Day Work Week: State of Play in 2026
📊 Key figures 2026
Over 200 French companies have adopted the four-day week. In the UK, the 2022 pilot programme showed a 22 % productivity increase and a 57 % turnover reduction among participating companies.
- 🗓️ Compressed model — 40 hours in 4 days (10-hour days). Same workload, higher density.
- 🕊️ Reduced model — 32 hours in 4 days. Reduced workload, maintained salaries.
- 🔄 Rotating model — The company operates 5 days but each team member works 4 different days.
- 🌡️ Flexible model — The 5th day is worked if necessary (peak activity) but remains the exception.
Impact of the 4-Day Week on Seminar Planning
| Classic format | Problem with 4-day week | Recommended solution |
|---|---|---|
| Monday evening → Friday morning | Friday not worked | Monday evening → Thursday evening |
| Wednesday → Friday | Friday absent for some | Tuesday → Thursday (2 nights) |
| 5-day annual seminar | Hard to fit in a working week | 4-day seminar aligned with working days |
| Friday afternoon team building | Friday = day off | Thursday afternoon or Wednesday morning |
4-Day Week and Seminar Culture: Fewer Events, Better Quality
- ⬆️ Quality over quantity — Fewer events but each with a higher budget and better preparation.
- 🎯 Sharper focus — With fewer days available, each seminar must have an ultra-precise objective.
- 💡 Format innovation — The micro-seminar (2–4h) fits perfectly into a 4-day working pattern.
- 🌱 ESG alignment — Fewer trips thanks to better-targeted, less frequent seminars.
Some pioneering companies have integrated the seminar into their 4-day logic: one day per quarter entirely dedicated to a team seminar, replacing weekly recurring meetings.
Practical Tips for Planning Seminars in a 4-Day Week Context
🗓️ Consult teams upfront — if rest days vary across the team, start by mapping common availability before choosing dates.
📅 Favour mid-week slots — Tuesday–Wednesday–Thursday remains the widest consensus window in most four-day models.
⏱️ Shorten seminar days — in a compressed week context (10-hour days), a 9am–5pm seminar day may feel light. Adapt accordingly.
🌐 Think hybrid — if some team members are on a different rotation, provide a remote participation option for key sessions.
📊 Measure impact — leverage the measurement culture that often accompanies the four-day week to evaluate the ROI of each seminar.
❓ Frequently Asked Questions
Does the 4-day week make residential seminars harder to organise?
Not necessarily. It simply requires adapting the days. Tuesday-to-Thursday seminars (2 nights) are becoming the new standard for 4-day companies.
How do you manage an annual seminar when rest days vary across teams?
Designate a special 'seminar week' where all employees, regardless of their usual schedule, are mobilised. Plan it 6 months ahead and make it an anticipated event.
Does the 4-day week favour micro-seminars?
Absolutely. Short formats (2–4h) integrate seamlessly into dense working days. A monthly afternoon seminar is often more effective than a full day per quarter.
