BOSTON (AP) -- Supporters of two ballot questions that would raise the minimum wage and create a statewide earned sick time policy in Massachusetts say they're planning to deliver a quarter of a million signatures needed to put both questions on the 2014 ballot.

The labor-backed Raise Up Massachusetts Coalition plans to hold a rally in front of the Statehouse before dropping the signatures off at Secretary of State William Galvin's office.

Wednesday is the deadline for certified signatures to be delivered to Galvin.

Backers of another proposed question that would expand the types of bottles covered by Massachusetts' 1982 bottle deposit law also plan to announce on Tuesday the number of certified signatures they've collected.

Other proposed questions would repeal the state's 2011 casino law and undo a new law linking future hikes in the gas tax to inflation.
