Me a few months ago: "I need to take a PTO day tomorrow."

Boss: "What for?"

Me: "It's P."

She never asked again.

Please Turn Over?

(I'm guessing you mean Private Time Off?)

It means Personal Time Off, essentially any time an employee has a paid day off work. (There's also unpaid PTO)

Basically paternity / maternity leave, sick leave, vacation, jury duty, bank holiday, or whatever else is in the company's PTO policy...

"P."?

Personal as in PTO is personal time off

Where I work the P in PTO means "paid"

Pretty sure it's Paid Time Off at least here in the US

Both terms are used with identical meaning referring to shared leave pool instead of separate vacation and sick leave (“annual leave” is sometimes used for this purpose, but sometimes, e.g. federal service, equivalent to “vacation”); IME (which may not be representative) paid is somewhat more common than personal for the shared leave pool.

Confusingly, paid time off (with the same abbreviation) is also sometimes used in the more obvious sense encompassing all or most paid leave (including some or all of things like bereavement, company/public holidays, paid time for administrative shutdowns, etc.)

(All of this is in the U.S.)

No, it is "Personal." To differentiate from other types of paid days off that we get. (Bereavement, religious holidays, etc...)

And I'm also in the U.S.

Citing Wikipedia doesn't negate the fact that my company calls it "Personal." And since I wrote the original comment, I'm probably more familiar with my company's terminology than Wikipedia.

Ah, just making sure you meant your company and not the US. Glad we reached an agreement.
