Yeah, the federal system for sure has that built in...actually to the point of being borderline unfair for the GS employees who spent their whole career in a high COLA area since COLA isn't included in the calc (but is for WG employees for some reason). But every time you see a headline about some ridiculous firefighter/cop retirement it's almost certainly a local jurisdiction that didn't close the loophole (but probably has now!). After working in the federal government and now working with some local jurisdictions it's interesting the range of professionalism you get at the local level. Some up there with the best of the federal government, but many just shockingly unprofessional and poorly run.I haven't heard of that happening in my area as the rules prevent it. Even if someone makes 3X their annual salary, the retirement calculation is based on the annual salary. I would have to believe that any jurisdiction that has rules to the contrary would quickly resolve such a loophole. The Feds and most law enforcement and firefighting agencies generally use the base salary amount times a high 3/high 5 to get the primary amount that goes into the pension formula. I would also have a problem with someone gaming the system in that way - although it's hard to blame them if the rules allow it!
