They're pretty common in municipal governments where I'm at, but they're pretty small at first.

They call them "longevity payments" and you get like 8 bucks for every month you've been with the city.

So the first year you'll get 96, the second you'll get 192, third 288, etc. But by the time you reach retirement ages, if you've been with the same city it gets to be a few thousand. It's good for people like secretaries and parks workers who don't make as much, but also don't tend to jump cities as often.

Someone like a planner or engineer may only be with the city 3 years before moving on, so they never get a big bonus, but they also tend to make a lot more money.
