I wonder how much all those retired farriers will lose, as they apparently still have a couple working for the water department (Union contracted positions) this in spite of the fact, that the city hasn't owned a horse in 50 + years.. 
Hmmm, I was going to suggest they would care for Chicago PD's horses but the more I think about it ...

Two different city departments, ain't no way the union will allow water department employees to work on police department horses.
