Accrual Caps vs. Forfeiture — Critical Difference
| Policy type | Legal in Washington? | What it means for you |
|---|---|---|
| Accrual cap | Yes — always legal | You stop earning new PTO at the cap, but existing balance stays intact |
| Use-it-or-lose-it (with advance notice) | Yes, if clearly written in advance before PTO is earned | Unused PTO forfeited at year-end if policy clearly stated this before PTO was earned |
| Retroactive forfeiture | Not allowed anywhere | Employer cannot zero out PTO you already earned without prior written notice |
