Sources said work at the Dharuhera factory stopped since today morning and all the workers are staging protest inside the plant.
The strike broke out after the management discontinued services of about 50 contract workers, the sources said, adding the workers had also opposed to being shifted from one production line to another.
The number of contract workers removed by the company could not be ascertained as Hero Honda officials were not available for comments.
The sources said workers have been opposing the company's move to shift a bulk of production to its newly opened third plant at Haridwar, where Hero Honda plans to produce its high volume models, including Splendor and Passion.
The contract and casual workers feared losing their jobs after the planned shift in production to Uttarakhand. They have been joined by the regular workers in the strike.
Hero Honda manufactures Splendor Plus and CD Deluxe models from the plant, which has a total of about 6,500 workers. The plant has a production capacity of about 5,000 units per day.
