Called in sick to lean staff

At my SC 75% of the management or anyone with permissions left on a 3 week leave to a different state. I run all of the Pick for the warehouse but can barely get out of bed from covid. I called in sick but I think my other PA and her PG will too and theirs no one to cover the positions in the building since all the AM staff is also gone. What happens in this situation since it was clearly a resource planning error? I am a PG btw, my PA is in a different state.
