The last time I worked in a job with HR there was a discrepancy on my hours, I can't even remember what it was exactly but I had to ask them to fix it 3 times which involved standing in a line during my lunch because that was the only time they'd make themselves available and then they magically figured it out once I asked if I needed to get my manager involved. I'm convinced the only thing they actually get training on is how to fire people.
