Kapilvastu: Jagadamba Prasad Chaudhary, chairman of Free Sugar Mill Workers’ Union at Mahalaxmi Sugar Mill in Kapilvastu, has filed a case in the labour court, Butwal, against what he called unilateral and biased retirement handed him by the factory management. The management committee of the mill has been made the defendant in the case. The mill has been closed for the past three weeks due to disputes between the workers and mill management committee after the committee gave retirement to four persons including Chaudhary. Three of them have been reinstated in their jobs.
