PTO (Paid Time Off)

Employer-provided paid leave that can be used for vacation, illness, or personal reasons.

Paid Time Off (PTO) is leave provided by an employer that employees can use for vacation, personal days, sick time, or other needs without losing pay. Many companies have moved toward a single unified PTO balance rather than separate vacation and sick day banks.

The amount of PTO matters for total compensation, but how it's structured and enforced matters as much. An employer offering 20 days but with a culture where taking more than 10 is implicitly discouraged has a worse effective offering than one with 15 days that genuinely encourages use.

Unlimited PTO has become a widely advertised benefit, particularly at tech companies. Research consistently shows that employees with unlimited PTO take less time off on average than those with fixed amounts, due to social pressure and unclear norms.

Accrual mechanics matter. Some employers front-load PTO at the start of the year. Others accrue it over time. If you're starting in November with a trip planned in February, the accrual model matters enormously.

Questions to Ask About PTO Before Accepting

  • How much PTO is offered, and does it increase with tenure?
  • Is PTO front-loaded or does it accrue over time?
  • Does unused PTO carry over year to year, or is it use-it-or-lose-it?
  • Is PTO paid out upon departure? (Required in California, Illinois, Montana, and some other states.)
  • If the policy is 'unlimited,' what is the actual average taken by employees?
  • Are there blackout periods when PTO cannot be taken?

PTO Payout Rules by State

Whether your employer must pay out unused PTO when you leave depends entirely on state law. California, Colorado, Illinois, Montana, Nebraska, and North Dakota treat accrued PTO as earned wages — your employer must pay it out at separation regardless of company policy. Most other states allow companies to set their own forfeiture rules. Know your state's law before leaving any job with a significant accrued PTO balance.

Unlimited PTO: The Reality

Unlimited PTO policies — where there's no cap on how much time you can take — are increasingly common, particularly in tech. The pitch is appealing: trust employees to manage their own time. The reality is more complicated. Research consistently shows that employees with unlimited PTO take less time off than those with fixed accruals, because the absence of a balance removes the psychological trigger to use it and creates social ambiguity about what's actually acceptable. Before accepting a role with unlimited PTO, ask what the average employee actually takes in a year. Anything under 15 days at a company claiming 'unlimited' is a red flag.

PTO vs. Sick Leave vs. Personal Days

Employers structure paid leave in different ways, and the structure affects how you use it. Unified PTO banks lump everything together — you use the same pool for vacation, illness, and personal appointments. This gives you flexibility but can create pressure to 'save' your balance for actual vacation, discouraging use when you're sick. Separate sick leave plus vacation is better for workers in states with mandatory sick leave laws, and removes any guilt about using sick days for their intended purpose. Personal days are a smaller, discretionary pool layered on top. When evaluating an offer, understand which structure you're being offered — 15 days of unified PTO is functionally less than 10 vacation days + 7 sick days + 2 personal days.

Example

A candidate receives two offers: Company A offers 15 defined PTO days; Company B offers 'unlimited PTO.' After asking current employees how much they actually take, she learns the Company B average is 10 days. She negotiates Company A up to 18 days and accepts — getting more real time off than the unlimited policy would have delivered.
