Chennai: Samsung Electronics is set to invest an additional ₹1,000 crore at its factory in Sriperumbudur on the outskirts of Chennai, Tamil Nadu industries minister TRB Rajaa said on Friday. The fresh investment would create an additional 100 jobs, reinforcing their faith in the labour force of Tamil Nadu, the minister said in a post on microblogging platform X.The South Korean electronics giant is making the investment despite recent labour protests at the plant over wage revisions, union recognition, and work conditions.The company has been battling labour issues with the workers and the management at loggerheads. Most recently, the Sriperumbudur plant, which produces TVs, refrigerators, and washing machines, saw worker protests after a wave of suspensions in February. That was the second instance of a labour standoff at the facility within six months.It followed hundreds of workers at the facility staging a five-week protest last September, demanding higher wages and recognition of their union. Following the strike, Samsung agreed to address several of the workers' demands.Samsung did not respond to ET's queries.The latest announcement coincides with Tamil Nadu's strong industrial performance, as outlined in the 2025-26 policy note from the state's Industries, Investment Promotion and Commerce Department.Between May 2021 and March 2025, Tamil Nadu attracted ₹10.14 lakh crore in investments, creating 3.2 million jobs across sectors such as automobiles, semiconductors, technical textiles, non-leather footwear, and food processing.The state now hosts 31,517 operational factories - the highest in India - ahead of Maharashtra's 20,739.
