Since President Obama called for an increase in the federal minimum wage 14 months ago, seven states and Washington, DC have passed such an increase, according to The New York Times. Meanwhile, 34 other state legislatures have started debating the issue and activists in another eight states are looking to get proposals for minimum wage increases on voter ballots, the newspaper stated. Companies that could be affected by minimum wage increases include McDonald's (MCD), Burger King (BKW), Wendy's (WEN), Jack in the Box (JACK), Dunkin Donuts (DNKN), and Sonic Corporation (SONC).
