I guess if your money is better than my health, then only you can make that choice.
What is childish is saying you will come to work knowingly sick with Covid and infect others.
Also i step up quite nicely for the people who work for me. I have no problem getting my hands dirty helping out when someone is not here while out sick, and also have no problem letting them work OT to make up for it if need be, but i understand not all companies will do that. But if they knowingly come to work infected with Covid, they will most probaly be fired.
But at the end of the day, you and ONLY you can make the choice not to infect co workers by coming into work with Covid.
