McJob

McDonald's may even sue the OED to take McJob out of the dictionary but that will likely not help the cause of the word itself - a McJob will remain a McJob complete with all depreciatory connotations until the nature of a McDonald's job fundamentally alters.

Its interesting how a word after being around for a while acquires a life of its own and not even purging it from the dictionary will kill it. In fact, the use McPower to bully OED would make the McJob even more Mc (if there is such a thing). Taking the OED by the horns may be one thing, but the power of the masses these days is vested in Wikipedia where a McJob after a disclaimer about neutrality is described thusly:

McJob is slang for a low-paying, low-prestige job that requires few skills and offers very little chance of intracompany advancement. Such jobs are also known as contingent work. The term McJob comes from the name of the fast-food restaurant McDonald's, but is used to describe any low-status job - regardless of who the employer is - where little training is required, staff turnover is high, and where workers' activities are tightly regulated by managers. Most perceived McJobs are in the service industry, particularly fast food, coffee shops, and retail sales. Working at a low paying job, especially one at a fast food restaurant, is also often referred to as flipping burgers.
