A section of employees are at loggerheads with the management at CD maker Moser Baer's Noida unit demanding revision in bonus and wages.

However, the company said no work has been affected as it is only a small group of employees who are protesting.

"Unfortunately, a very small group of approximately 150 associates from the packaging section of one of our optical disc plants out of around 10,000 associates have come up with unreasonable demands," Moser Baer India CEO (Blank Optical Media & Consumer Electronics) Bhaskar Sharma said.

He said no work has been stalled and the company is in discussion with the protesters since there is no union representing the agitating employees.

"We are currently in discussion with them and looking at their concerns. Our manufacturing plant is in operation," Sharma said.

Sources said a larger number of employees were agitating on demands of bonus hike and wage revision.

The company's revenues for the year ended March 31, 2011 stood at Rs 2,682.93 crore, of which the storage media products business contributed Rs 1,633.10 crore.

The company claims to be the world's second largest manufacturer of optical media solutions commanding 16 per cent development, manufacture and supply of optical media across the globe.

In the Indian market, Moser Baer forayed into the burgeoning domestic optical storage market with the launch of the Moser Baer label in 2003.

The company manufactures the entire spectrum of optical storage media products including Recordable Compact Discs (CD-R), Rewritable Compact Discs (CD-RW), Recordable Digital Versatile Discs (DVD-R), Rewritable Digital Versatile Discs (DVD-RW) and blue laser discs (HD-DVD and Blu-ray) and has an annual production capacity of over 3 billion units.
