I'm not sure what larger effect the decision of Paizo's staff to unionize will have on the larger TTRPG industry (likely little if any), but the 30+ staffers at Paizo are hoping that Paizo will recognize their union.
Staff say they are “underpaid for their labor, required to live in one of the most expensive cities in the United States, and subjected to untenable crunch conditions on a regular basis”.
Most everyone in the RPG industry is underpaid for their labor, in large part because the profit margins are not as large as many would like them to be.
In any case, 30 some odd members does not make for a powerful bargaining unit. It is, however, likely, that Paizo has the largest staff of non-managerial job titles in the industry.
