Don't laugh!
Well, at least try not to laugh.
It's okay. I laughed, too.
Picketers for Hire: The strange business of protesting jobs that may be better than yours
[...]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 F, and they're protesting the working conditions inside the new Wal-Mart grocery store.
[...]In Dyson's [Walmart] market, the air-conditioning is cool, business on this day seems brisk, and the employees seem not so miserable; two checkers chat it up as they ring up customers.
This is not lost on the picketers outside.
It's okay. I laughed, too.
