Although the 240 hour leave carryover limit applies to most federal employees, there are special rules in certain categories. For example, employees stationed overseas may carry over up to 45 days, and members of the Senior Executive Service, senior level, and senior scientific and professional employees may carry over up to 90 days (even higher limits may apply to some SES employees). Also, most postal service bargaining unit employees may carry over up to 55 days and postal executive and administrative schedule employees may carry over up to 70 days.
