Dear Kharwal,
Yours is a nascent organization, and as such, the employees might be a mixed group of people, i.e., a combination of fairly experienced individuals and freshers in similar job profiles. Therefore, your present salary structure would be more or less on par with the Market Labor Wage Structure prevailing in your industry as a whole.
Reasons for Salary Revision
The need for a revision of the existing salary structure within a short span of time since the inception of the organization might have been prompted by different reasons, such as enhancing the competitiveness of the company by motivating the current workforce, attracting new talents, removing certain anomalies in the existing salary structure, and introducing Potential Performance Appraisals to retain star performers, among others.
Misconception of Salary Hike vs. Salary Revision
The advice of your experienced HR friend, though cautious based on frugality, seems to be, in my view, a misconception of salary hike versus salary revision. A salary hike is incremental based on performance appraisals at certain intervals or upon the passage of a predetermined time duration, like six months or one year, depending on the employer's practice. The employer is the sole judge of this. Simply put, it is the same percentage of a hike in any one component of the salary structure, mostly a raise in the basic salary only.
On the contrary, salary revision is a modification of the entire salary structure, including all primary components. To distinguish, a 15% increment relates to a 15% hike in any one component of the salary structure, mostly the Basic, whereas the same 15% salary revision implies a 15% hike in all components. The mismatch between the current pay/wage structure and the Market Labor Wage Structure acts as the general determinant of salary revision. In the case of unionized or bargainable categories of employees, salary revision is determined by Collective Bargaining. For other employees, employers undertake a periodical study of the pay scale patterns of similar job profiles in the market, and the salary structures are carefully designed or modified accordingly. Sometimes, to reward and retain senior employees who are frozen at the maximum scale, "longevity increase" or "stagnation increment" is also provided for in the salary revision.
By and large, you can opt for the salary revision of your employees, notwithstanding the fact that your firm is less than one year old. What is important is your ability to pay and the sustained contribution of employees to the growth of the company.
