I'm fairly new to playing this game but I don't think it is normal for the police strike to last 23 years worth of play.
The city built is under 70k people and I have several large or deluxe stations. (This is the strike that has lasted 23 yrs.)
Another city I built has population of about 110k and both fire and health are on strike (about 2 years)
Every time I increase the funding in both cities nothing happens.
Please can somebody tell me how to end a strike
