My late father worked for Morton Salt for close to forty years. Then Morton got a new 38 year old CEO and he wanted to shake up the company. He figured out that the employees over 55 years old tended to be the highest paid and if he got rid of all of them it would goose profits and he'd be a hero to Wall Street so he did it.

For a quarter or two it worked and then the company descended into a death spiral and he was fired. My Dad got another good job and did OK. Poor Morton Salt never recovered, they've been sold a half dozen times and aren't even the largest salt company in America anymore.
