Proposed rules from the Office of Personnel Management would allow federal employees to use up to 12 weeks of sick leave a year—up from the current 13-day limit—to care for a family member with a serious health condition. The entitlement would be in addition to the 12 weeks allowed for similar purposes under the Family and Medical Leave Act, which provides unpaid leave. OPM says that using paid leave would have several advantages in addition to continued income while helping the relative, including avoiding the possible negative effects of prolonged unpaid leave on the employee’s health and retirement benefits and within-grade pay raise eligibility. The rules will be effective after a comment period that ends March 27, probably soon afterward.
