Are Any Agencies/Employees Safe??

This administration claims there are agencies/employees that at safe, and will not be affected by government layoffs. From what I’m seeing, that doesn’t seem to be the case. I am a nurse for the VHA, and we are exempt from the hiring freeze because we are deemed “essential”. No one knows what’s going on. No one is really talking about it because management does not know what’s going on. Has anyone heard or seen anything showing what agencies may be exempt from layoffs?? Every day things change. The anxiety is real. Working as a Fed was supposed to be the job everyone wanted because it was deemed secure. Based on what I’ve seen online, that’s no longer the case.
