It’s no secret that America’s workers are busy. Between family obligations (like sick kids or ailing parents) and necessary errands (like annual physicals and renewing driver’s licenses at the DMV), few can dedicate paid days off to real vacation time. Fortunately, some companies have found a way to remedy this situation. They call their solution “unlimited PTO,” and it combines paid sick days and personal/vacation days under one “paid time off” umbrella for employees to utilize at their own discretion.
