>since Walmart's strictly-enforced corporate policy until about 2 years ago was that they would not pay above minimum wage

We both worked for Walmart as cashiers on and off between about 2008 and 2013, in Rapid City, Pierre, and Aberdeen, South Dakota, and the starting wages were consistently above minimum wage. I've never heard of this policy before, especially since different positions always had different starting wages and all were minimum wage or slightly higher.

Again though, even if our Walmart employments were minimum wage jobs:

    min_wage * hrs_worked > -union_init_fee + (min_wage * hrs_worked) - (union_due * weeks_worked)
