Hi,
Bonus is essentially a "share in the profits" of the organization. To streamline many dissimilar practices in industries so that dissatisfaction over the payments by employers to the employees could be contained. In the past, such payments were dependent on the whims and facies of the employer, and there was no thought about rationality in payments and equitability.
As an answer, the country passed the law, "Payment of Bonus Act 1965," and it became mandatory for an employer to pay a bonus in terms of the act which provided mode and modality for calculating a bonus. I am attaching a brief note on the subject. The note covers the topic but cannot provide all details.
Ex-gratia is a term that refers to any payment made by the employer "gratis," which means, "of his own free will," and under no obligation of any law. The practices regarding this are many, and I will cite only some so that the conceptual difference is easily understood.
1) When the profits do not support a large bonus, the employer may give some amount from out of the revenues of the firm, in acknowledgment of the workmen's contribution.
2) On an event of significance to the organization, like completing a specific period of existence, completion of a large export order, etc.
3) Any other reason that is NOT binding on the employer, but the employer "wishes" to make such a payment.
All in all, these two terms look related, but in reality, they are conceptually different! Are we now clear?
