Without delving into the points raised by Dinesh & Nathrao, please note that there are numerous gaps in the information you provided. Consequently, I assume you understand that ANY & EVERY suggestion offered by any member could either be non-actionable or misleading.
Details Needed
Can you provide more details about the situation/issue such as:
1. What's the sector/domain your company is in?
2. What's the employee strength?
3. Since when have you been facing this problem?
4. Regarding your statement about an "employee leaving the company without serving the Notice Period," what is the actual scenario? Is it a case of employees absconding, resigning and leaving without serving the full notice period (meaning only partial serving of NP), resigning and leaving without serving even a single day of notice period, or something else?
You mentioned being a Company Secretary. Therefore, I assume you have some knowledge of law and its issues. Hence, your last line, frankly, surprises me - "My question is can we file a case and get the money from them." You should be aware that anyone can file cases, not just civil suits but also criminal ones. However, whether the desired outcome will be achieved depends on various issues, angles, and aspects - some of which may not be within your control.
Just ask YOURSELF the same question - what are the chances that such a step will ensure you get any money back, especially in a civil case? 90%? 50%? 20%? 10%? You must realize it can never be 100%. So the decision is yours (or rather the company's) on the next step to take.
Also, based on what you have disclosed so far, I BELIEVE the company has MANY skeletons in their cupboards, which are likely to emerge when ex-employees start revealing information in court and it becomes public knowledge. Will the company be prepared for this scenario if it materializes?
Another aspect that companies (or their advisers) often overlook is the damage that such immature and incomplete actions cause to the company's image. Do you think your future hiring endeavors will be successful? Specifically, if you are in the IT sector, you can be certain that retaining clients will become challenging... I believe you can understand the reasons why.
I recommend advising your management to think rationally rather than emotionally in such matters - it's easy to get carried away.
All the best.
