I’d say agree to the pay raise with the provision that any federal employee still on the old CSRS system by the end of the fiscal year be automatically moved to the FERS system. The manpower savings will more than cover the costs of the pay increase and all those billets held up by civil servants retired in place for 10+ years will make a world of difference for younger feds blocked out of promotions and innovation by the entrenched older feds
CSRS ended in 1983 or 1985 I forger which.
Very few CSRS’ers left.
