While the automobile giant is offering a hike of Rs. 6,500 a month, similar to a settlement at the manufacturer's Dharuhera plant, workers are demanding what their counterparts at Honda and Maruti get.
"Workers at Honda have got a salary hike of Rs. 14,700 per month. Maruti has given a substantial hike as well," said Bhim Rao, general secretary of the Hero MotoCorp workers union.
"We have already stopped taking tea from the plant canteen and are wearing black badges on our arm as a mark of protest," Rao added.
A Hero MotoCorp spokesperson, however, denied any tension or deadlock over the issue in an email response.
