Dear Ranjeetha,
Any person who happens to be an all-in-one HR in an organization has to face such an inevitable crisis situation, particularly when the organization is relatively smaller and in its early stages of growth. The rule of thumb would be the management style. Often, it would be much more difficult for such an HR executive to even initiate a free and convincing dialogue with the CEO, who could be obsessed with growth only through cost-cutting, about the natural expectations of the employees for a hike in their remuneration over time. Your statement that you are paying minimum wages is an indication of the mindset of your management in this regard. Payment of minimum wages is an act of minimum compliance only, and as such, its continuance for years cannot retain employees or make them committed to the organization in the long run. It may be ideal for seasonal or intermittent nature of work only, as such workers are free to seek alternative employment elsewhere. However, in the case of regular employment within an organization, expectations of a fair share in the growth and development of the organization, improvement of their standard of living, the desire for an increase in real and monetary wages on par with similarly placed workers in the same industry elsewhere, and questions of seniority-based wage differentials would naturally arise in the minds of workers who have been paid minimum wages for an extended period.
If the management chooses to ignore such a justifiable demand of the workers with a callous attitude, not only will efficient employees leave the organization in search of better opportunities, but the remaining employees would also become highly demoralized and demotivated, ultimately affecting the quality of the products or services of the organization. I understand that you are not the ultimate decision-maker. However, as an HR professional, you can be tactful and persuasive to convince the management that if they do not become part of an amicable solution, they will become part of the problem. Finally, remember that employees do not leave companies but leave managers only.
Kind regards
