Stock up on your cheeseburgers now: Organizers behind a series of strikes in the fast food industry over the last few months are promising another round Thursday, claiming there will be events in 100 cities, including Boston; Chicago; Denver; Hartford, Conn.; Houston; Los Angeles; Memphis, Tenn.; New York; Oakland, Calif.; Raleigh, N.C.; and Tampa, Fla.

The strikes are being organized by the nonprofit group Fast Food Forward, which last led a round of strikes in late August. The group is calling for a base $15 an hour wage at restaurants like McDonald’s, Wendy’s and KFC, many of which only pay minimum wage.
