TRENTON, N.J. -

A quarter-million minimum wage workers in New Jersey will get a raise at the stroke of midnight Wednesday.

That's when a change in the state constitution kicks in, raising the state's minimum wage from $7.25 to $8.25 per hour.

Six in 10 voters approved the increase in November.

It also guarantees future minimum wage hikes to the lowest paid workers as the cost of living rises.

A dozen other states are raising their minimum wage above the federal minimum of $7.25 on Jan. 1.

President Obama has proposed increasing the federal minimum wage, but Congress has not agreed.

New Jersey Policy Perspective, a liberal think tank based in Trenton, said 254,000 workers will see a wage boost in their next paycheck. Most of them are working adults, not minors.
