CTC means Cost to Company (CTC) is the salary package of an employee. It indicates the total amount of expense an employer (organization) is spending for an employee in a year. CTC is not the actual salary of an employee, it also includes all the facilities an employee is getting during the service period.
I don't no what you mean by legality for this.This practices used in all over industries to attract workforce and showing how much an employer spending to an employee.
