It can also be for reasons like staffing pressures, crazy schedules, and even policies that admin makes. These employees are intelligent people who care about their jobs, their patients and how things actually function. Ive seen it in my years in healthcare and as part of union negotiations. Sometimes the issues are things like a bad supervisor who rules with stupidity instead of logic. Cuts corners to meet budget demands to please their boss higher up. When management causes foreseeable problems, employees get angry. And if you push them far enough, long enough, they will walk.
I worked in medical records as a medical coder. Middle management got financial $$$ bonuses if they kept their budgets below a certain $ figure for their department. Our boss purposely shorted us certain essential items to do our core job (including necessary coding books that were update every year by the AMA and other national medical publishing companies, which cost a fortune). She also never sent us to continuing education seminars, instead making us squeeze in time in our packed, overworked regular schedule to do online quickie courses. Often times, we were so busy, we could not complete the yearly hospital accreditation online courses we were required to complete. Most of us did them at home, online, on our personal time. No OT allowed.
By these measures, she came in under budget and solely benefited. Time to go shopping and get that lovely little XXX that Ive been just dying to get.
Yea, I am not surprised at all if these staff walked enmasse. Sounds like management pushed them beyond their limit.
