Dear Satya,
Since you have mentioned that your employer is discriminating amongst the employees in disbursement of bonus, I presume that the Payment of Bonus Act,1965 is applicable to the establishment.
Regarding your queries that as to whether the employer can stop bonus for some employees and can pay to the selected employees, my reply to your query is that the employer cannot deprive of bonus to his employees, who meets the eligibility criteria I.e.if he had worked for 30 days in that year and is within the ceiling limit of salary under the Act.
