Work at the Tata Motors Nano factory in West Bengal's Singur area would remain suspended for another day on Tuesday with the company asking employees to stay away, the fourth consecutive day that the plant has been shut. 

"Our workers will not be reporting to work today," a Tata Motors spokesperson said in a statement.

There was no work at the factory on Friday, Saturday and Monday due to the indefinite protest by the Trinamool Congress-led opposition that is demanding return of 400 acres taken for the project from "unwilling farmers".

Tata Motors is slated to roll out the world's cheapest car from its factory in Singur, 40 km from Kolkata, in October.
