BENGALURU, India: Tata Consultancy Services' decision to lay off more than 12,000 employees is being seen by industry experts as an early sign of a much larger shift in India's US$283 billion outsourcing sector, one that could eliminate up to half a million jobs in the next few years as artificial intelligence adoption accelerates.

TCS, India's largest private employer, described the layoffs—about two percent of its workforce—as the result of skill mismatches rather than AI-related productivity gains. Still, industry analysts say the move, which affects roughly 12,200 mid- and senior-level roles, marks the most significant job cut in the company's history and foreshadows similar actions across the sector.

AI is increasingly handling tasks like basic coding, manual testing, and customer support—functions that have long formed the backbone of India's IT services model. The industry employs 5.67 million people and contributes over seven percent to India's GDP, with far-reaching economic impact through associated job creation and consumer spending.

"We are in the midst of a massive transition that will transform white-collar work as we know it," said Ray Wang, founder of Constellation Research.

Experts say the most vulnerable employees include people managers with little technical expertise, software testers, and infrastructure management staff responsible for basic tech support. Gaurav Vasu of UnearthInsight estimates that between 400,000 and 500,000 professionals, 70 percent of them with four to 12 years' experience, could be laid off in the next two to three years.

"This fear may hurt consumer demand for tourism, luxury shopping, and delay big-ticket investments like real estate," Vasu warned.

The middle layer is particularly exposed. According to staffing firm Xpheno, TCS and peers such as Infosys, HCLTech, Tech Mahindra, Wipro, LTIMindtree, and Cognizant together employ over 430,000 workers with 13 to 25 years' experience. "At the moment, they may appear like the big fat middle layer," said Xpheno co-founder Kamal Karanth.

Cost optimisation is driving the trend, said Jefferies analyst Akshat Agarwal, as clients demand productivity gains, often achievable with AI, allowing the same work to be done with fewer staff.

TCS, which had over 613,000 employees before the cuts, has said it is preparing to be "future-ready" by investing in emerging technologies, expanding into new markets, and deploying AI at scale for clients and internally. It did not say how many job losses were AI-related or why redeployment was not possible.

For some employees, the layoffs have been devastating. "It is very difficult for people my age to get new jobs," said a 45-year-old TCS worker in Kolkata. Others cited declining performance bonuses, stricter "bench" policies limiting time without a project, and low morale.

The outsourcing industry, which has powered India's middle class since the 1990s, is facing weaker revenue growth as global clients delay spending and demand tighter cost control. Nasscom, the industry body, said AI and automation are now "at the very core of how businesses operate."

"With AI, for the first time, the onus is on the individual to reinvent or re-skill themselves," said former Tech Mahindra CEO CP Gurnani.
