Excuse the ignorance, but what do nurses even do?
TLDR: Don't be fooled by job titles. "Professionals" aren't always amazing at what they do.
Like any job - it depends on the person and workplace.
I worked in an ER for 6 years. When that place was flooded with patients, Docs needed all the support they could get and good nurses made insanely busy days run smoothly for everyone. Even the lazy nurses had to be on their toes, but could make for some headaches when the place was jamming.
With that said, on slow days....they just stood around gossiping or complaining and made tons of cash for doing so.
Nurses on the inpatient floors who did not have to worry about an emergency every 5 seconds were able to stand around even more while making their cash. The hospital nurses were unionized as well for added protection.
From my own personal experience in my primary care office, they don't do anything but take my blood pressure, scowl, and let you wait.
My brother's a physician in an ICU ward. He has been exposed to corona and was already quarantined, and is now back at work pulling triple duty as his two partners are in bed with corona - one of whom is in his 70's. He's burnt out, his practice is now tasked with ownership transition during private practice office closure, but he hasn't posted a picture of himself at work letting anyone know.
I'm an attorney and the egomania in my profession is a problem as well, and it's why I roll my eyes at any "look what I do" posts. I can assure you that the attorneys who are looking for attention tend to over-lawyer deals just to make things difficult, and are usually overstating their qualifications. We're mostly glorified paper pushers.
Some Teachers fall into this category and need reality checks on their constant demand for hero worshiping. I'm in a state where they get paid more than most, are provided a state pension, have incredible state health benefits, have union protection as well, and tons of mandated free time including all of the various seasonal breaks and days off.
