I guess this may not be a right time for firing an employee. Most gambling houses are working hard to make use of the free time of people around the world who stuck at home due to isolation and lockdown reasons. I mean some gambling houses are recruiting more people to cover new gambling demands. I am not sure how well rocket.run have planned and executed in this particular scenario but if I were an admin, I might have taken a different decision if that old manager was good enough to work for some more time.

When they are sick due to covid19, for example, admins will not have any other choice expect appointing a new manager. So, we cannot assume what happened really behind the screens.
