Now a days It usually happens in the company that company hires a employee with good package.. at that time employee is new to business and with no experience.. after probation period/sometime employee leaves the job... so now in that case what can be done by employer? can he ask him for both 3 months salary + 1 month notice period... ? Is it that employer can not tell him to do both 3months salary+1 month notice?.. what other things can be done?
