So can I stop paying my VEBA "tax" for the next five years?

After all, we negotiated this for the benefit of the guys 54 and older - the young guys will bear your healthcare costs on their shoulders. But now you get to work for another 5 years.

I want my VEBA money back, dammit!

(And yes, I know it's not a lot of money to me or anyone personally, but it's the principle)
