Query Regarding Cash In Hand Salary Proof

Theres a doubt ,my appointment letter doesn't show cash-in-hand word instead has mentioned total annual employment would be 120000. Is it must that the appointment letter should contain cash in hand payment of Rs 10,000 per month. Any suggestions ? As I am applying for canada immigration, would there be any problem? As I am informed to submit my employment documents including salary slips, bank statements, cash vouchers and pay slips. but I was receiving cash in hand and theres no salary break up with the appointment letter. Please friends suggest me what should I do ?
