What if I want to quit the union?

Thank you for proving my point. Why do you feel it necessary to take a personal stab at someone simply because they feel differently than you about unions?

If I am unhappy at my job I will either try to change the conditions that are not OK with me or find a different job.

Years ago our hospital was sold to a for-profit company. They came in with "patient focused care", cut staffing, forced nurses to float to units where we were not competent, didn't allow us access to O2 flowmeters at night, laid off pharmacy and wrote up nurses for missed meds that hadn't arrived.

So WE called CNA. Now we have safe staffing ratios and a committee to address patient care issues.
AND we got improved pay and benefits.

If we hadn't had a way to work to improve our conditions I may have had to get another job.

There are lots of jobs for nurses and nurses are employable in other fields too.
