Maybe a trend:

The Jimmy John’s restaurants here are known for serving attitude with their sandwiches. Many of their young workers wear nose rings, beards and dreadlocks, and the shops sport mottoes like “The Customer Is Usually Right” and “Subs So Fast You’ll Freak.”

But recently, the employees at the 10 shops here have started to exude more attitude than management would like. Some of the 200 workers wear T-shirts that say, “Wages So Low You’ll Freak,” and many are backing a campaign to unionize the shops, which compete with Subway and Quiznos.

The unionization drive is one of the few efforts to organize fast-food workers in American history. Employees will vote Friday, and if the union wins, organizers say they will seek to unionize fast-food workers in other cities.

The issues that have roused the Jimmy John’s workers are typical of what many low-end service-sector workers face: earning the $7.25-an-hour minimum wage or slightly above that, working unpredictable and often short shifts and dealing with their bosses’ wrath when they call in sick.
