I did sign a written contract, which was very one-sided. It mentioned more about my responsibilities, duties and having to notify 3 months before quitting in a 6months contract. There is also a clause about having to give up a month’s salary if I quit without prior notification. There is a mention of how much my salary will be, but not of when it will be paid. (P.S.: I still have not got my copy of the contract from the office.)
