The San Francisco Chronicle:

San Francisco officials have secured $525,000 in back wages and penalties from the owners of a Chinatown restaurant accused of forcing employees to work 11-hour days, six days a week for less than $4 an hour, with at least one doing double duty as a maid at the owners' Telegraph Hill home...

One employee... said she knew nothing about minimum wage or overtime laws when she got the job in 2005, shortly after immigrating from the Taishan region in southeast China.
