The national capital largely remained unaffected by the nation-wide strike called by trade unions on Wednesday, though most industrial workers stayed away from work.
Metro and the Delhi Transport Corporation (DTC) services functioned normally despite the strike call.
Officials said no trains have been affected in the national capital, but some Delhi-bound trains from Odisha and West Bengal could be affected.
Widespread intermittent rains in the national capital also reduced the intensity of the strike.
The industrial areas of Mayapuri and Wazirabad witnessed protest march.
At the ITO, workers affiliated to left unions gathered in support of the general strike called by 10 central trade unions against the central government's "anti-worker" policies.'
CPI(M) leader Subhashini Ali, who took part in an agitation at the ITO, said they were protesting against the "anti-labour" laws of the Centre.
"We are protesting against the anti-labour laws of the Modi government, and the labour codes they plan to introduce which are against the welfare of the workers. They even want to sell a Maharatna like Bharat Petroleum (Company Ltd) and move towards privatisation," she said.
Members of 10 central trade unions -- including AITUC, INTUC, CITU, AICCTU, CUCC, SEWA, LPF, -- along with various sectoral independent federations are participating in the nationwide strike, Amarjeet Kaur, General Secretary, AITUC said.
The trade unions have claimed around 25 crore people are participating in the strike to protest against the government's "anti-people" policies.
