About 8,000 contract workers of state-owned Punjab Roadways and PRTC went on indefinite strike Monday, demanding regularization of their jobs.
Private buses, however, continued to operate in the state.
More than 2,000 buses from the state-owned Punjab Roadways and Petsu Road Transport Corporation (PRTC) were left off the road, said Punjab Roadways, chairman of the Punbus/PRTC Contract Workers’ Union, Resham Singh Gill.
He said there would be only 200 to 300 buses of regular workers on the street.
The indefinite strike call caused inconvenience to many passengers who usually travel on state buses.
Protesting workers held demonstrations in many places, chanting slogans against the state government for failing to meet their long-standing demands.
They also threatened to besiege the residence of Punjab Chief Minister Amarinder Singh in Siswan in Mohali on Tuesday if their demands were not met.
Mr Gill said they were assured in July and August that their demand for regularization would be met.
Despite two cabinet meetings since then, the issues remain unresolved, he added.
The state government’s “apathetic” attitude to their demands forced them to strike, Gill said.
In addition to regularization of jobs, the protesters are also demanding an expansion of the fleet from about 2,500 buses currently to at least 10,000.
