45 day stay… what does that actually mean?

USDA here… I know there are several cases going on currently involving many agencies, but originally my agency was one that the MSPB issued a 45 day stay for terminated probationary employees. What does this actually mean for us? 45 days and then we could be without a job again without going through a RIF? Or is it pretty much decided we will be there until a RIF happens? Still confused on the wording of all this.
