At Walmart, PPTO stands for Protected Paid Time Off, which is designed to provide employees with the flexibility to take time off when unexpected events occur in their lives, such as medical or family emergencies. This type of PTO is meant to support employees during unforeseen circumstances. In addition to PPTO, Walmart also offers regular PTO, which allows employees to take time off for holidays, family time, and other personal needs. Both types of PTO provide employees with the opportunity to balance their work and personal lives effectively.
