Besides non-executive employees, over 10,000 engineers are also on an indefinite strike from Tuesday seeking absorption of officers on deputation from the department of telecommunication.
BSNL Employees union general secretary V A N Namboodri said, "There is a massive response to the call and more than 200,000 workers are on strike. Most of the offices are closed as nobody is available. Repair work was also affected."
The employees union will meet today to decide further course of action.
The All India Graduate Telecom Officers Association of Engineers, which has called for an indefinite strike, said they will continue with their protest.
