No. They pay you from their corporate bank account. That's not borrowed, smart guy.
All of YRC's profits are essentially focused on paying down the loan. You're not paid with actual borrowed money, as you are undoubtedly paid from the coffers, but what they pay you can't go towards financing equipment or paying down the loan.
You deserve your money back. I'm just explaining why you're unlikely to get all of it back during the next contract negotiation. And if the bank doesn't agree with the terms, they can exercise an option to foreclose on the loan and demand all of their money from YRC. YRC can't pay that, and it would bankrupt them. If you're okay with that, then go ahead and vote no. It's your choice, but make it a well informed choice.
