It seems like your comment would be better directed towards weak or absent nurse unions, instead of individuals. I had countless nurse and physician friends go to their hospital directors/HR/managers during the pandemic "I need a raise because I have absorbed the load of 3 other workers and am working harder than ever." Not only were they refused, many instead received 10-33% pay cuts, with hospitals citing increased Opex costs despite decreased staffing, significant government assistance, and increased volunteer (0-cost) help.
It'd also be enlightening for people in this thread to have hospital executives explain how they have some of the highest patient numbers in history yet they're hemorrhaging so much money their physicians had to take pay cuts.
Nurses, due to their profession having relatively low barriers to entry yet requiring years of operational knowledge to truly be effective, need collective bargaining. Nurses do strike, and nurse strikes are actively occurring on the U.S. West Coast. However, the unions they represent are small and have little power overall. For a strike to be successful you need solidarity from a majority of workers in the area you want to impact. You also need buy-in from the hospital/region that union nurses will provide superior care to non-union nurses. Something that's hard to do when your average executive thinks that the most complicated thing a nurse does is sticking a patient.
