Hi Kiran,
In our company, we don't have a salary advance scheme, but we have the policy of an emergency loan. In this scheme, we basically provide one month's salary if the employee has been working for 6 months. However, if the employee has been with our company for more than 1 year, we offer 3 months' salary or more (as per management decision) based on the employee's requirement.
This loan is completely interest-free.
I hope this information is helpful.
Thanks, Nipuna
