A hack for scheduling your PTO to get the most days off has gone viral. The post suggests that if you schedule your PTO around company holidays you can use 18 PTO days, to get 46 days off.
It's sounds sketchy, but it's not actually stealing time from the company. It's strategically planning your vacation days around days that you already get off- for holidays and weekends- to get the most time off at a time for your vacation.
It's a pretty smart way to plan vacations IF you can get that days approved.
