Many of the workers involved have hours that change on the whim of their supervisors. Employees who aren't team players don't get hours.

Do you have any evidence at all that this will be the case here?

I was speaking generally... but I think its going to be pretty difficult to avoid in an organization like Walmart, with its low-margin and strong emphasis on efficiency and controlling costs, to look at a sheet that says an employee is 2 minutes from a delivery point, but instead we had to send a truck 30 minutes out to deliver a package... it's going to be hard for that manager not to take that as a willingness to help.

Once you have a sheet with times and delivery points for each employee.. it becomes a measure of the employees willingness to assist. If other employees are willing to drive 10 minutes, and you're not willing to drive 2 minutes, it raises the question of why.

And that question is definitely going to be asked if the alternative (30 minutes for regular delivery) results in an additional cost to the company.

But as I said, we'll have to wait and see.
