From The Intended Irony Department:

All Work and No Pay

Picketers have been standing outside a Wal-Mart in Henderson, Nev., holding signs protesting the discount chain's alleged maltreatment of workers. But these people aren't protesting because they believe in what they're doing. They're getting paid for it, albeit at a niggardly rate, reports the Las Vegas Weekly:

They're not union members; they're temp workers employed through Allied Forces/Labor Express by the union--United Food and Commercial Workers (UFCW). They're making $6 an hour, with no benefits; it's 104 [degrees] F, and they're protesting the working conditions inside the new Wal-Mart grocery store.

Hmm, now we know why unions favor a legally mandated minimum wage. It prevents anyone form hiring even cheaper picketers to picket the picketers.
