An unfair labor practice is a violation of state or federal labor law itself, things like refusing to bargain in good faith, retaliating against an employee for union activity, or bypassing the union to make unilateral changes to working conditions.
In California, most public sector ULP charges are filed with PERB: the Public Employment Relations Board. The deadlines are strict, the process is specific, and the record you build at the administrative level shapes everything that follows.
Sometimes a single incident raises both a grievance and a ULP. Pursuing both simultaneously, through different channels, with a coordinated strategy, is part of what experienced labor counsel provides.
GRU Law represents California labor organizations in unfair labor practice proceedings before PERB and in grievance arbitrations. DM us or t.ly/fRqfu to get started.
