In a non right-to-work state like NY, it means you have to pay dues to a union that negotiates on your behalf. It can very well end up negotiating for things you don't want, or are even actively against. For instance, a teacher may be in favor of merit-based promotion and compensation while they are obligated to pay dues to a union that pushes for seniority based pay.
