Learned Mr. Vasudevan has elaborated and made the matter crystal clear.
Your concern is employee should be rewarded with Incentive/bonus from day 1; while it is the employer's discretion and can link it to the performance.
In today's context the employee should be smart and must have adaptability, flexibility, situational management, persistence etc.
In corporate world it is acknowledged fact that money motivates. Speak to the corporate in corporate language.
Approach the decision making authority e.g. Head of sales if you are in sales, and make a presentation that the employee shall be all the more inclined to perform better if he/she knows there shall be a reward of performance incentive/bonus and for probationers a scheme may be formulated with reasonable targets compared to a confirmed employee so that they taste the money and get into the habit of it by the time they earn their confirmation of service they are seasoned and hardcore performers and become an asset for the organization.
There are companies which still offer moderate salary but huge and high incentives and some them hardly spend anything on training, R&D etc but the vintage of their employees is in tens of years and they earn lacks of rupees in incentives. People long to join them but until they expand there is no vacancy. e.g. Micro Pharma.
