The agitating employees, numbering more than 90, are also demanding recognition of their union.
"They were staging an sit-in-strike inside the campus since yesterday. Today, we have detained them," a senior police official told PTI.
One of the agitating employees, who did not want to be named, claimed the management had recently dismissed some workers following a strike and sought reinstatement of the workers and recognition of the employees' union.
When contacted, a company official said efforts were on to solve the issue through negotiation with the employees. "It is unwarranted. They have been staging protests just to seek the attention of media", the official said.
