A four-day week eases much of what pushes people out of veterinary jobs. Whether it actually lowers veterinary staff turnover is still unproven.
The strongest evidence comes from outside vet med. A 2025 trial covering 2,896 employees across 141 organizations moved staff to a four-day week with no pay cut. After six months, burnout was lower, and job satisfaction, mental health, and physical health had improved.
Inside vet med, the evidence is a patchwork of owner reports, one vendor survey, and a few case studies. They point in the same direction, with real caveats about who is reporting and how the schedule gets built.
What Does the Research on Four-Day Weeks Actually Show?
The 2025 four-day week trial, published in Nature Human Behaviour, compared its 141 participating organizations with 12 control companies that kept their usual schedules. Each participating organization reorganized its work before the trial began to protect efficiency on fewer days. The paper measures well-being rather than resignations, so it explains why a shorter week might reduce quitting without proving that it does.
Vet med's turnover problem gives the question weight. In its Stay, Please study, the American Animal Hospital Association (AAHA) put average annual turnover among veterinary team members at 23%, and 30% of respondents in clinical practice said they planned to leave their current position within a year. Job flexibility landed among the top six factors keeping people in place, alongside fair compensation and appreciation for their work.
What Are Veterinary Practices Reporting?
The most direct vet-specific number comes from a 2026 survey of 114 companion animal practices by AIV Vet, an infusion pump supplier. Asked which retention strategies had actually worked, practices ranked four-day weeks second, behind only big raises.
The survey's own write-up flags selection bias, since practices that made the schedule work are likelier to respond than practices that gave up on it. Two respondents add color. A Detroit-area owner reported no clinical staff turnover in the 14 months since switching, and an Albuquerque owner who paired the schedule with raises said it came down to choosing between expenses, because turnover had been costing more.
Melissa Magnuson, DVM, took a related route. She owns three New Hampshire practices, sits on the AAHA board, and cut weekend hours after COVID. She told Veterinary Practice News that retention improved, especially among single mothers who valued predictable schedules and weekends with their families.
Dr. Magnuson changed how much of the week the practice occupies rather than how many days each person works, which hints that predictability carries part of the retention value.
A 4 Day Week Global case study describes Kronobäck's Veterinary Clinic in Sweden, which moved its veterinarians and nurses to a four-day week at the same pay in 2022. Owner Ida Wallin says the 22-person clinic has spent nothing on recruitment since and reports a 1% sick-pay rate. The account is promotional and comes from the owner, with no baseline figures and no turnover rate.
What Has to Be True for a Four-Day Week to Hold?
Dropping a day does not remove the work. AIV's write-up lays out the two basic options: compress the same caseload into four longer days, which raises fatigue, or cut weekly capacity, which cuts revenue. The practices reporting results found a third path: the same weekly output from fewer days. The Nature Human Behaviour trial worked the same way, since every participating organization reorganized its work before starting.
Equine practice shows how common the compressed version already is. A 2022 compensation survey cited by EquiManagement found four-day weeks at 25.3% of equine practices in their busiest quarter and 37.3% in their slowest, usually as four 10-hour days.
Before changing the schedule, a practice can work through a short checklist:
- Name the fifth-day plan. Decide who covers emergencies, callbacks, and refills when the doors are closed, and tell clients before the change, not after.
- Protect the long days. Four 10-hour days can leave a team as tired as it was before, so build in real breaks, staggered lunches, and a cap on overtime.
- Check the fill rate. Veterinary Practice News suggests aiming for an appointment fill rate near 85%, and treats a lower rate as a sign a practice may have hours to trim.
- Measure before and after. Track turnover, overtime, and a monthly pulse survey so the pilot produces your own data instead of someone else's anecdote.
Because the published evidence in vet med is still anecdotal, the most useful move for a practice leader is a one-quarter pilot with a single team, such as the technicians, compared against the quarter before. For the wider set of levers that keep teams together, Hound's staff retention guide covers how to calculate turnover and which compensation, togetherness, and development moves reduce it. A look at vet sabbaticals covers another way practices are rethinking time away.
