Yes, that's the headline of this Texas Tribune article. Texas taxpayers will be forced to spend an additional $105 million just to cover the raise, but that's not enough for the prison lobby.
The union claims, among other things, that "poor pay" leads to corruption. That's right, people aren't responsible for their own corruption, they can blame their salary.
If prison employees aren't getting paid enough, maybe they should go look for a different job.
Libertarians know what this all comes back to: the war on drugs. Without that, we'd have a lot fewer prisons, prisoners, and prison employees, lower taxes, and a lot less corruption to worry about.
