“… The union is pushing to reinstate a bizarre perk known as air time done away with by the 2012 pension reform law. Under the practice, public employees could purchase pension credits for years they didn’t work, which in turn boosted their pension benefits. … The union argues that eliminating the practice violates the so-called California Rule, which limits the ability of governments to modify pension benefits without making up for modifications in some other way. … While the case is still pending before the California Supreme Court, Californians should root for a reasonable interpretation of the California Rule that enables sensible changes to be made.”
