as per Act we have to give and they have to eligible to get leaves under contract labour regulation and abolition Act. but majority of establishments they need not give any leaves to contract labour. it is violation of indian laws.

Please suggest Employee is eligible for only last three yrs of
leave encasement as per the rule ,if the employee has not availed or
en-cashed is leave from his DOJ (01/04/2008)it would get lapsed.

Sir kindly suggest me if contractors are not ready to pay the under minimum wages rate.as a principal employer what will be our next step.
other hand contractors are given excuse at the time of work contract the MW rate was different because the MW rate are revise within every six month.
