Applied at healthcare for Unknown

I've been feeling uneasy at my healthcare job lately, and today I noticed that HR has started interviewing current clinical staff. As a support staff member, I'm not directly involved in these interviews, but the atmosphere has definitely shifted. I'm starting to wonder if I should be concerned about my own job security and whether I should update my resume just in case. I know it's always a good idea to be prepared, but I don't want to jump to conclusions or panic. I’ll take some time to update my resume and stay ready for whatever happens.
