Flexible time off (FTO) is a paid leave model with no accrued balance. Employees don’t bank days as they work. They request time off, a manager approves it against the needs of the business, and nothing accumulates on the books.

It is closely related to unlimited PTO, and many employers use the two names interchangeably. The ones that distinguish them usually mean something specific: unlimited implies no ceiling at all, while flexible signals time off that is uncapped on paper but still approved, still subject to coverage, and often guided by a stated norm such as “most people take four to five weeks.” Choosing “flexible” over “unlimited” is frequently an attempt to set expectations the word “unlimited” oversells.

Why employers adopt it

The recruiting pitch is autonomy and trust. The finance case is more concrete, and worth stating plainly because it drives most adoptions.

Where accrued vacation is treated as an earned wage, an accrual policy creates a liability that sits on the balance sheet and must be paid out when someone leaves. If nothing accrues, there is nothing to pay out.

That’s a legitimate reason to adopt FTO. It’s also where the legal risk concentrates, because the saving only materialises if the policy is genuinely non-accruing — in substance, not just in name.

The California rules

California is the jurisdiction that tested this, in McPherson v. EF Intercultural Foundation. The court accepted that an unlimited, non-accruing policy can be lawful — but found this employer’s wasn’t, and ordered payout of unused vacation under Labor Code § 227.3.

The court set out what a valid policy needs to do:

• Be in writing
• State clearly that time off is not additional wages for services performed, but part of a promise of a flexible schedule
• Spell out the rights and obligations of both sides, including what happens if an employee doesn’t schedule time off
• Give employees a genuine opportunity to take time off or work fewer hours
• Be administered fairly, so it doesn’t operate as use-it-or-lose-it or produce inequities

The employer failed on nearly all of them. There was no written policy, managers expected roughly two to six weeks a year, requests needed approval, and peak-season leave was discouraged. Decisively, the employees testified they never understood the policy to be unlimited, and the court gave that considerable weight.

The lesson generalises beyond California: an FTO policy that functions like a capped allowance is a capped allowance, whatever the handbook calls it.

Canada: the statutory floor doesn’t move

FTO is lawful across Canadian provinces, but it cannot displace statutory entitlements — and this trips up US employers extending a policy northward.

Employees remain entitled to the minimum vacation time for their province, and to vacation pay calculated as a percentage of earnings (commonly 4% at the base tier, rising with service). That obligation is non-waivable, and unused statutory vacation is still payable when employment ends. In practice a Canadian FTO policy has to run alongside a tracked statutory minimum rather than replacing it.

The same principle applies to statutory sick leave wherever it exists. Entitlements created by law sit outside your PTO policy, with their own accrual, notice and record-keeping requirements. An uncapped policy doesn’t remove any of that.

Does it actually give people more time off?

The popular claim is that unlimited policies suppress usage, because without a balance to spend nobody knows what’s acceptable. The evidence is more equivocal.

Namely’s analysis of its client base found employees on unlimited plans averaging 12.09 days a year against 11.36 days on limited plans — a small edge for unlimited, and a reversal of its earlier finding where unlimited users took fewer days (13 against 15).

The honest reading is that the label matters less than the implementation. A policy with a stated norm, visible senior usage, and a floor performs very differently from one that just removes the balance and says nothing.

Designing one that works

• Put it in writing, and say explicitly that time off is not deferred compensation
• State a norm — a target range gives people permission that “unlimited” withholds
• Consider a minimum. Mandating a floor of, say, 15 days directly addresses the under-use problem
• Keep statutory leave separate — sick leave, parental leave and provincial vacation minimums are tracked entitlements, not FTO
• Watch for drift. If approvals are routinely refused or the real-world average quietly becomes a ceiling, you have an accrual policy with extra legal risk
• Track it anyway. FTO removes the balance, not the record. You still need usage data for coverage, for fairness monitoring, for FMLA designation, and to show you gave people a genuine opportunity to take leave

Frequently asked questions

Is FTO the same as unlimited PTO? Usually, though “flexible” often signals a policy that is uncapped but still approved and guided by a norm.

Does FTO have to be paid out when someone leaves? In the US, not if the policy is genuinely non-accruing and meets the conditions above. In Canada, statutory vacation pay remains owed regardless.

Do employees take more time off under FTO? The data is mixed and the differences are small. How the policy is communicated matters more than whether it has a cap.
