As a consultant in a Pvt. Ltd. company, the appointment letter states that my work hours are from 10 AM to 6:30 PM with Saturdays and Sundays off and no leave entitlement. I have not been signing in the muster, and I am on a zero-plus arrangement. They deduct 10% tax from my fees. The agreement is for one year and can be terminated with one month's notice from either side. There are no other benefits provided. Is this term acceptable?
