WASHINGTON (AP) — President Barack Obama’s plan to raise the minimum wage for federally contracted workers is winning praise from unions and labor activists, but it could take a year or more before any hikes take place and the impact may not be as widespread as some advocates had hoped.

Obama announced in his State of the Union address Tuesday that he will sign an executive order setting the minimum wage for workers covered by new federal contracts at $10.10 an hour, a hefty increase over the current federal minimum of $7.25.
