Sorry, but I think you're off base. I know quite a few long standing nurses in a variety of areas of nursing and most are in agreement with the idea that family comes first. As it stands, 30% say they will not work during a pandemic (the poll thread) and 21% are undecided. I'm hardly alone in this stance. Further, you have no idea what my education or experience may be outside of what is in my profile. Just because I am a CNA at this time and moving into nursing school doesn't mean that I don't have degrees or experience in other medical or related areas. For all you know I might be a psychiatrist or other healthcare professional looking to move into a different medical field of expertise. I'm not saying I am or I'm not- I'm merely pointing out that you really have no idea.
Again, I'd wager that more people than not DON'T have reliable long term childcare if they thought about the potential situations during the situations we're talking about here. Daycares and schools may well be closed during these situations. Something to really think about. If all the nurses who currently rely on daycare and school for their childcare needs were to think "Gee, I shouldn't be a nurse because I don't have someone nearby who can raise my kid if disaster strikes and I have to live at the hospital for awhile." I think we'd be looking at a far greater and more serious nursing shortage than has been going on.
Do you also feel that nurses who are having a harder time finding full time work in their current area should be moving their families across the country to fill the holes in places where shortages are still a problem?
