It probably depends on the status. If they are a Fed and will probably get paid and still have a job, no. But, if they are a fed contractor and will not get paid or have no job to go back to, yes (or they are in a support industry).

Depending on how long this goes, does it count as a “loss of a job”? Is APIA the only agency with protection for job loss?

I’ve seen rematches because a host parent lost a job—is this basically because you can rematch for any reason or do agencies have a specific policy about it?
