Castle Industries (Private) Limited followed Shalimar Paints' Howrah plant that declared suspension of work on Wednesday.
Workers found the notice at the plant gate at the Kalyani Industrial Estate area here in the morning.
Plant manager Bishnu Kumar Choukhan said, "We have not been getting any order for a year. At this situation, how can the plant run? Still, the management has been paying wage to the workers."
The 80 odd workers of the factory used to come only to sign in the attendance register for the past one year as there was no work, Choukhan said.
Workers demonstrated in front of the factory after seeing the suspension of work notice.
INTTUC Nadia district president Sunil Kumar Tarafdar said, "We shall sit in a discussion with the labour department so that the problem is solved.
