Paying the worker bees more because they've unionized might potentially take money away from the nonprofit's important mission. Not to mention the salaries of senior staff, who are paid over a million dollars a year. [0]
Of course they are. It's a good reminder that non-profits are very often just an arm of capital, whatever their legal status is, and that they will exercise capital's authority to try to suppress workers' rights.
Unions destroy innovation and change in businesses. Look at how teachers unions fight against performance based pay and make it impossible to fire bad teachers. I love that cancer centers are resisting communism.
Innovation and change are not worth as much as providing a living wage to those who work for you. If you value nebulous innovation over the quality of life of real people, I don't know what to tell you.
