Since April 2026, Kerala has been hit by a quiet labour shock. Migrant workers from West Bengal and Assam left for Assembly elections in their home states. Many have not returned. What began as election-season movement has exposed a deeper weakness in Kerala’s economy.
The state has depended for two decades on workers from eastern and north-eastern India to run construction sites, plywood units, restaurants, hotels, farms and fishing harbours. Kerala’s own workers have moved away from low-paid manual work. The gap was filled by migrants. That bargain now looks less secure.

Kerala migrant workers and election disruption
The immediate trigger was political. West Bengal voted on April 23 and 29. Assam also went through Assembly elections. Reports from Kerala say the outward movement was unusually large this time, especially among workers from West Bengal and Assam. Industry associations reported shortages in construction, hotels, restaurants, plywood and fishing.
The numbers must be handled with care. Kerala does not have a precise live count of migrant workers. Older estimates put the migrant workforce in the range of several million. But official registration captures only a part of it. The Athidhi portal allows migrant workers, employers and contractors to register and is meant to give the Labour Department a working database. Its existence itself points to the state’s unfinished task: it depends on a workforce it still does not fully see.
The return migration was not just about voting. Reports from the ground linked it also to anxiety over electoral-roll verification, especially in West Bengal. Many workers feared that absence from home during the process could affect their place on the rolls. For workers from districts where identity, citizenship and documentation are politically charged questions, this was not a minor fear. It took precedence over wages.
The effect was immediate. Construction sites slowed. Agriculture was hit. The Perumbavoor plywood belt felt the shock sharply. The sector operates with overwhelming dependence on migrant workers, many from West Bengal. When workers left, production was disrupted.
Kerala labour shortage hits plywood, hotels and fisheries
The labour shortage did not occur in isolation. Kerala’s restaurants were already under pressure from LPG supply and price disruptions. For a migrant worker, this matters. A restaurant or hotel under stress cannot offer assured work. If work is uncertain in Kerala, and political, family or seasonal reasons keep him home, the case for immediate return weakens.
The monsoon adds another brake. Outdoor work slows. Construction schedules stretch. Marine activity is affected. The fishing sector shows how deep the dependence runs. A 2025 ICAR-Central Marine Fisheries Research Institute study found that migrant workers make up 58% of Kerala’s marine fisheries workforce. At Munambam harbour in Ernakulam, they account for 78% of the mechanised fishing workforce. Migrants also form 50% of post-harvest workers and 40% of fish-market workers.

This is not a marginal labour pool. It is the operating system of several sectors.
Employers now face the other side of labour mobility. For years, Kerala’s higher wages pulled workers from West Bengal, Assam, Odisha and Bihar. Now those workers have more alternatives and better bargaining power. Employers across southern India have had to offer higher wages, travel support and other incentives to bring workers back. The old assumption that workers would leave, vote and return has weakened.
Migrant wages and bargaining power
The shift is visible in wage negotiations. Skilled workers know that Kerala cannot replace them quickly. Local reserve supply is thin. Contractors cannot conjure a workforce after the monsoon. Restaurants cannot automate kitchens overnight. Plywood units cannot run on sentiment.
This does not mean every worker will stay away. Many will return because Kerala still offers better wages than most source states. But the certainty has gone. The employer who assumed automatic return must now negotiate.
The deeper failure is institutional. Kerala has treated migrant labour as available, but not always as a workforce to be retained. Registration remains incomplete. Access to decent housing, health services, grievance redress and portable welfare is uneven. This matters because migrant workers are no longer tied to one destination. If Kerala wants them to return after elections, festivals, heatwaves or family visits, it must offer more than higher daily wages. It must offer predictability.
That is not charity. It is economic infrastructure.

Kerala economy cannot take migrants for granted
Migrant workers are not only labour inputs. They are consumers. They rent rooms, buy food, use transport, visit clinics and sustain local shops. A part of their income is remitted home, but a part circulates in Kerala’s local economy.
Their absence hurts twice. Output falls first. Then local demand weakens.
The social contradiction is stark. Kerala’s high literacy and human development achievements coexist with a labour market that depends heavily on poorer workers from other states. Many Malayalis will not take informal manual jobs at prevailing conditions. Many prefer education, migration, white-collar work or waiting for better employment. That is a rational choice for households. It is a constraint for the economy.
If the shortage persists, small businesses will face higher wage bills and delayed projects. Restaurants will raise prices or cut menus. Builders will miss deadlines. Plywood units will lose orders. Fish landing, sorting and market work will suffer. The cost will eventually reach consumers.
Higher wages are not the problem by themselves. Kerala should not build growth on cheap and insecure labour. The problem is the absence of a system that recognises migrant workers as permanent contributors to the state’s economy.
Kerala needs full registration, portable welfare, decent housing, safer worksites, health access and grievance mechanisms. It also needs employers to treat return migration, elections and festivals as predictable labour-market events, not sudden shocks. A state that depends on migrant labour must plan for migrant lives.
The lesson from this episode is plain. Migrant workers were treated as replaceable because they were politically invisible. Their departure has shown otherwise. Kerala’s economy does not merely use migrant labour. In several sectors, it rests on it.
