Apple’s ugly labor problems aren’t limited to its Foxconn factories, and they aren’t going away.

The labor rights group Students and Scholars Against Corporate Misbehaviour (SACOM) first exposed the wave of employee suicides at Apple’s Chinese contractor, Foxconn, and the grueling conditions in which hundreds of thousands of employees work. SACOM has regularly revealed Apple’s failure to abide by its so-called code of conduct, and along with another watchdog group, China Labor Watch, has monitored Apple’s failure to live up to its announced intention to clean up sweatshop conditions at its factories in China and to stop the use of indentured student labor.

In April, China Labor Watch reported that two more Apple/Foxconn workers had committed suicide by jumping from buildings to their death. China Labor Watch also found labor law violations at ten other Apple suppliers, including Pegatron.

Now SACOM has released a new report that details the serious labor rights violations at another Apple supplier, Biel Crystal, which reportedly makes 60 percent of Apple’s touch screens. SACOM reports that five Biel Crystal workers employed at its Huizhou factory have killed themselves since 2011. One possible cause is the stress of working horrific hours—11 hours a day, seven days a week, with only a day off in a month. This is a gross violation of Chinese labor law, which limits overtime to 39 hours a month. The Biel Crystal employees work more than twice as much overtime as the law allows.

When will American consumers wake up to Apple’s crushing exploitation of Chinese workers?
