Twenty-six work safety inspectors in Chongqing municipality have submitted a joint resignation letter to the local government because of their low salaries and heavy work load.

"It's difficult to support a family on such a poor salary, which is the main reason for our resignation," Ma Huayu, safety supervision office director in Shihao town, Chongqing's Qi Jiang county, told China Daily yesterday.

Every inspector except one in Ma's office jointly submitted the resignation letter to the county and town government last week, he said.
