BOSTON (AP) — Harvard University President Lawrence Summers says the university will raise the wages of its lowest-paid workers, an issue that sparked campus protests last year.

He said Thursday that the school would adopt a "parity wage" plan with the goal of increasing the salaries of several hundred custodians, security workers and dining hall employees to between $10.83 and $11.30 an hour — higher than the $10.50 "living wage" demanded by students who occupied the former president's office for three weeks last spring.

Harvard plans to complete the new policy by March 31 at a cost of about $3 million. The pay raises must still be negotiated with unions.
