The salaries for public employees of most of Chicago suburbs are public information. I'm not guessing: there's a web page that lists them all, by name. I know this because some friends and I were comparing notes on the salaries of teachers in our respective suburbs yesterday, on Slack. I don't have the link handy, but if you'd like to wager against me on this, I'm happy to take your money. :)
I do not understand your math on workdays. I am terrible at math, but it sure sounds to me like 48 work weeks in a year is 240 work days, not 200, or 190.
Sorry, I went through my browser history and it's Arlington Heights, not Buffalo Grove (they're adjacent and I get them confused). You would have won the bet!
What was the highest normal teacher salary you saw in Buffalo Grove? In Arlington Heights, it's $150,660.
