Unlimited PTO: What It Means and Where It Fails

Unlimited PTO removes the balance, not the obligations. In Europe and Australia the statutory minimum still has to be granted, tracked and paid at exit; in the US a policy that is 'unlimited' on paper but limited in practice can still owe vacation pay, as a California court found. What unlimited actually means, where it breaks, and how to run it so it survives an exit or an inspection.

Short answer

Unlimited PTO means no fixed entitlement and no accrued balance — so, in most US states, nothing to pay out when someone leaves. It does not remove statutory minimums: across the EU, the UK and Australia leave must still be granted, recorded and paid at exit, so a quantified floor has to sit underneath. In California a policy that was unlimited in name but capped in practice was held to owe vacation pay. Set a minimum, track days taken, and apply it consistently.

What “unlimited” actually changes

An unlimited (or “flexible”, “discretionary”, “open”) PTO policy removes the fixed annual entitlement and, with it, the accrued balance. Employees take the leave they need, subject to manager approval and business needs. For the employer the attraction is twofold: no liability on the balance sheet, because nothing accrues; and, in most US states, no payout at termination, for the same reason. For recruiting it signals trust.

What it does not change is any legal obligation to grant leave, to record it, or to pay for it when the law says so. Everything below follows from that.

Where it fails: the United States

In the majority of states the policy works as intended if it is genuinely unlimited, written, communicated and applied consistently. The failure mode is a policy that is unlimited in name only. In McPherson v. EF Intercultural Foundation (2020) the California Court of Appeal looked at an “unlimited” arrangement that was never written down, never explained to the employees concerned, and in practice limited them to roughly the same leave as colleagues on an accruing policy — and held that Labor Code §227.3 applied, so unused vacation was owed at termination. The court was careful to say that not every unlimited policy triggers payout, and set out what a defensible one looks like: written, clearly stating that leave is not a form of additional wages, telling employees how to take it, allowing enough time off that it is genuinely unlimited, and administered fairly.

Two further US traps. Mandated sick leave — state and city paid-sick-leave laws — must still be tracked separately, because those statutes have accrual, carryover and documentation rules of their own; “unlimited” does not satisfy them automatically. Outside the US the equivalent schemes are statutory and unavoidable: see sick leave by country. And transitions: when a company moves from accrual to unlimited, the balances already earned are wages in the no-forfeiture states and must be used or paid, not zeroed.

Where it fails: Europe, the UK and Australia

Outside the US the concept collides with a floor that cannot be moved. Across the European Union every employee has at least four weeks of paid leave that must be genuinely available, must be taken as rest, is protected if the employee was prevented from taking it, and is paid out at exit if untaken. A policy with no balance has nothing to pay out and no way to prove the minimum was honoured. In the UK the 5.6 weeks work the same way, and employers must keep records adequate to show the Working Time Regulations are being complied with. In Australia annual leave accrues under the National Employment Standards regardless of policy, carries over indefinitely and is paid at termination; “unlimited” can only ever be extra leave on top.

The practical answer everywhere outside the US is the same: a quantified statutory floor, tracked as usual, with the unlimited element layered above it. The US-company-in-Europe guide walks through what else changes.

The behavioural problem

The consistent experience of companies running unlimited leave is that people take less, not more, and take it unevenly: the confident take plenty, the anxious take none, and the number of days taken tracks the manager rather than the policy. Without a balance there is no anchor for “normal”. The result is burnout in exactly the people a generous policy was meant to protect, and, in Europe, a compliance problem when someone has taken fewer than the statutory minimum by December.

How to do it properly

  1. Write it down. State that leave is not a form of wages, that there is no accrual and no payout where the law permits, how to request it, and that it is genuinely unlimited subject to approval.
  2. Set a minimum, not a maximum. “At least 20 days a year” gives people permission and gives you a compliance check. In Europe the minimum is the national statutory figure or higher.
  3. Track every day taken, even with no balance. You need it for the statutory floor, for consistent treatment, for cover planning and for spotting the person on zero.
  4. Keep the statutory portion as a real accrual for employees outside the US, and treat the unlimited element as extra.
  5. Handle mandated sick leave separately where a US state or city requires it.
  6. Transition honestly. Pay or let people use balances earned under the old policy; do not reset them.
  7. Have leaders take leave visibly, and have managers review anyone below the minimum each quarter.
  8. Apply approvals consistently and record the reasons for refusals — inconsistency is the fact pattern that turns “unlimited” into “limited in practice”.

A clause to adapt

Flexible time off. [Company] does not set a fixed annual allowance of paid time off. Employees may take the paid time off they need, subject to approval and business requirements, and are expected to take at least [20] days a year. Time off does not accrue and is not a form of additional wages; where local law requires a minimum paid annual leave entitlement, that entitlement is recorded, protected and paid on termination in accordance with that law, and this policy applies in addition to it. Statutory sick leave is governed by the applicable statute. All time off is requested and recorded in [the leave system].

The honest summary

Unlimited PTO is a legitimate policy in most of the United States when it is written, real and consistently run, and an add-on — never a replacement — everywhere with a statutory minimum. It removes the balance from the books; it removes none of the record-keeping. If anything, it needs a better tracker than an accrual policy does, because you no longer have a number to argue about — only the record of what was actually taken.

Common questions

Do we owe a payout at termination under unlimited PTO?

In most US states, no, because nothing accrues — provided the policy is genuinely unlimited, in writing and applied that way. In California, the Court of Appeal in McPherson v. EF Intercultural Foundation held that an 'unlimited' policy which was unwritten and in practice limited still triggered vacation pay under Labor Code section 227.3. In the EU, the UK and Australia the statutory portion is always paid at exit whatever the policy is called.

Can we offer unlimited PTO to European employees?

Only on top of the statutory minimum, not instead of it. The four weeks (or more) required by national law must be identifiable, recorded as taken, protected from expiry where the law protects it, and paid out if untaken at exit. Most companies keep a formal accrual for the statutory part and treat the flexibility as an addition.

Why do people take less leave under unlimited policies?

Because the norm becomes ambiguous. With a balance, 20 days is a target; without one, taking leave feels like asking for a favour, and people calibrate to the least-absent colleague. The fix is a stated minimum that managers enforce, and visible leadership use.

Does unlimited PTO need to be tracked at all?

Yes — more carefully, in fact. You still need to know who was away when, to prove statutory minimums were granted in Europe, to show consistent treatment in the US, to plan cover, and to spot the people taking nothing. What disappears is the balance, not the record.
