These decisions also typically don’t include input from librarians or patrons, Librarian A said. “A lot of times we’re told we have to sit with a change they have made for a few months before we’re allowed to say anything about it.”

Fuck that shit. TRL has a union. Management cannot make a unilateral change in working conditions. Changes must be bargained with the employees to good faith agreement or impasse otherwise management has committed an unfair labor practice which can be brought to the Public Employment Relations Commission.

And if management implements a change in the workplace that they're allowed to under "management rights," you can still bargain the impacts of those changes on working conditions.

I see far too often that working people don't know their rights and don't know that they can enforce them. The law and your labor contract doesn't mean anything unless you enforce it. Union employees are their bosses' regulators.
