we have no medical leave-What is the entitlement for Govt Employees? Why leave has been denied to you?

Dear Sir,
we are getting 26 days of wages/month. the principal employer want to see the 26 days register attendance ..so the question of overtime is not permitted by principal employer. if any rules under the contract labor (central) is applicable please provide us
