Some bus drivers in Haiyan, Zhejiang province, went on strike on Monday as they were dissatisfied with their work hours and salary, Modern Gold News reported on Tuesday.

The strike started in the morning with nine bus routes operated by the city's Hongyun bus company and some other bus routes linking the suburban counties with downtown.

The drivers on strike said they had not had a single day of rest for more than a year and their wages were low.

An apology was posted on the company's official micro blog at 8:52 am on Monday, which said it was making efforts to solve the problem.

After coordination between the company and the drivers, the bus routes went back into operation at about 2 pm.
