It is in management's best interest, short-term to do so. No more discipline problems, no more staff grievances, no more performance and raise issues. All these issues will be included in the contract. Sally doesn't show up and Fran has to work for her three days in a row. The answer is in the contract.
Management has no decision to make.
The union will handle it or not. And will have failed the patients as well. And don't forget, techs and LPN's, to ask for the financial statements for the Union. I say Probably. Whatever happens I hope is in the best interest of the patients and staff.
