“Let’s get better wages in this country!” was the rallying cry Wednesday as workers nationwide took to the streets in demonstrations marking the four year anniversary since the last time the federal minimum wage was raised.

If wages see no increase during his second term, Obama will become the first president since Ronald Reagan who didn’t raise the minimum wage at all.

Currently set at $7.25 an hour, the national wage hasn’t had a boost since July 24, 2009 when President George W. Bush increased it from $6.55. Despite skyrocketing costs of living, a full-time worker earning the minimum wage is only making roughly $15,000 per year—far below a living wage in most parts of the country.

In honor of this ‘dispiriting anniversary,’—as Huffington Post’s Dave Jamieson writes—labor groups supporting a minimum wage boost have called for a National Day of Action with planned demonstrations in an estimated 30 cities across the country.

In Pittsburgh, protesters have reportedly shut down the street outside of a Target in the East Liberty section of the city. Other rallies are being held outside of a downtown McDonald’s and on the campus of the University of Pittsburgh Medical Center, among other locations throughout the city.

“Tell Panera bread we can’t live on bread alone,” one protester, Pastor Battle, said before an assembled group.

Under the banner Raise Up Massachusetts, a coalition of groups are staging rallies outside the locations of 13 employers of low-wage workers throughout the New England state including Wal-Mart, Dunkin’ Donuts, and Papa John’s. Advocates are calling for a gradual increase of the wage from $8 to $11 by 2015 and are also pushing for paid sick leave for all workers.

Demonstrators in Cleveland are marching on a local Wal-Mart at noon on Wednesday.
