A key Honda component factory in Foshan paralysed by strikes for almost two weeks is putting pressure on its school interns, who make up more than half of its workforce, to sign a letter saying they will not take part in the action.
Some of the interns say teachers at their vocational studies schools have threatened to punish them if they refuse to sign.
And those who do sign will be given a monthly pay rise of more than 400 yuan (HK$450).
About 200 interns from Guangdong were bused to Tao Yuan Secondary School in Songguang Township in Foshan yesterday to sign the letter.
Interns from different provinces would be asked to sign today and all of them would need to submit their signed letters by tomorrow, some of them told the Sunday Morning Post.
The letter, which was distributed on Thursday, asks the interns to promise they will stay at Honda Auto Parts and not to get involved in any strike or they will be punished according to the mainland's labour law.
