No implication. One union got a raise and the other seems to be following suit. The whole thing seems to be unfair right now but will likely be fixed:

The University Council-American Federation of Teachers, the union that represents UC-system librarians and non-tenure-track lecturers, including Reiterman, recently kicked off an effort, including an online letter-writing campaign and a couple of town halls, to persuade the system to confront what they’re calling a pay inversion. The union’s existing contract ends June 30, 2026, but union leaders are urging administrators to pay lecturers more immediately.
