It's good that you started thinking of welfare schemes for your colleagues. Specifically regarding education loans for your employees' children, I have some suggestions:
I'm not sure about the financial standing of your employer. If you can afford it, loans for diploma/degree and higher courses can be interest-free or offered as soft loans with nominal interest, repayable in EMIs starting when the children are employed. To ensure regular repayment, suitable conditions could be included in the Terms & Conditions, backed by certain securities.
1. If all of you are covered under EPF, the scheme itself provides for a partial withdrawal (non-refundable) up to a certain limit for their wards' education.
2. Almost all banks offer education loans for all courses from PUC and above, including courses abroad. Sometimes, applicants may face hurdles meeting the banks' requirements, which could be overcome if the employer acts as a guarantor appropriately. After all, banks are commercial entities, and their primary goal is to keep NPAs within acceptable limits, so the employer should facilitate quick loan approvals.
3. Employee Unions and Co-op societies also provide education loans from their funds, particularly for books, hostel fees, etc.
4. Employers can create schemes or partnerships with educational institutions to secure free seats for deserving wards/toppers by planning mutual benefits such as providing internships, free training, etc.
And you can continue with ideas like these.
