Wal-Mart must pay workers $78m

The world's largest retailer, Wal-Mart, has been ordered to pay at least $78m in compensation to workers who were forced to work during breaks.

A jury in a Pennsylvania court decided that Wal-Mart broke a state law by refusing to pay staff for the extra work they did.

The class action was brought by about 187,000 staff who worked for Wal-Mart between March 1997 and May 2006.

Wal-Mart said it was planning a "very broad-ranging appeal".
