They are striking on the weekend? For 2 days?
That's pretty comical, most big distribution centers are M-F, or sometime Sat, but most are closed on Sunday. Monday's are the biggest day in grocery, followed by Friday's, so it wont effect them much. And ALL the grocery companies use company fleet trucks to deliver to the stores, followed closely by the biggest company you never heard of C&S Wholesale Grocers who delivers about 90% of the food on the east coast to both DC's and stores. I personally know Rick Cohen, he's the 13th richest person in the US, and trust me, C&S isn't going to strike. The grocery stores will have PLENTY of stuff in them.
"No commerce, no banking, no shopping," how are the truckers going to shut down the banks? and the product is already in the retail stores, so it wont effect shopping. As a matter of fact its already in the distribution centers, so it wont effect the stores for weeks, if at all.
All this is going to do is get them fired from the companies that expect deliveries on those days, and since there are about 10,000 independent trucking companies in the US, I'm, pretty sure that they will be replaced in a heartbeat by either the major players, or another small independent.
This is a retarted strike if you ask me, and while I support their message its not going to effect any of us in any meaningful way.
