John Kasich Supports Unionization of Government Employees?

I was just watching the video of the Kasich ad that Modern posted earlier today and I’m completely baffled by the meaning of this quote from John Kasich:

“My father carried mail… it was very, very tough… but the job was something people could count on for a lifetime.”

Is he saying postal workers deserve tenure like college professors?

Is he finally admitting that his success in private life was only possible because of publicly-funded jobs like postal worker and congressman?

Or is he praising the job security enjoyed by postal workers and other government employees that comes from the hard work of labor groups like The American Postal Workers Union.

Here, again, is the ad. You tell me…
