الجواب وبالله التوفيق
As per the situation described in your question, the ruling depends upon where the money in that account is invested by your employer. If the money is invested in a haram or impermissible sources of earning then utilizing the profit earned on that invested amount is considered haram. If however the money is invested in a permissible source of earning then that investment and utilizing the profit from it will be considered permissible.
You should perform further research by talking to your employer and resubmit the question if needed.
واللہ اعلم بالصواب
