The Office of Personnel Management has issued interim rules to carry out several provisions already in effect under law, including one generally limiting federal employee back pay awards to a six-year statute of limitations unless a shorter limitations law applies. The change reflects language in the Defense Department authorization act passed last year that sought to settle many years of debate over what time limits should apply under the various laws under which federal employees might receive back pay awards. (The new rules also reflect a boost in the maximum federal physicians’ comparability allowance from $20,000 to $30,000 per year for those who have served more than 24 months, as provided in a law passed in 1998.)
