No, it is not the employer's prerogative to offer bonuses to the contractors that work for him or her. The vendor who has outsourced the personnel has the bonus burden. When the vendor is unable to pay the bonus, some companies provide a bonus to their contractors as a gesture of goodwill. This is regarded as ex-gratia or favour rather than a bonus. It is up to the employers’ decision in these scenarios; they are not legally obligated to give bonuses to their contractors.
