Big Bob--six-feet-four Robert McEllrath's waterfront handle--was heralded for his powerful speaking style, charisma, unifying vision, and negotiating prowess. President of the International Longshore and Warehouse Union (ILWU) for twelve eventful years, McEllrath retired in 2018 after nearly forty years as a union officer. More than just a telling of a storied career, Labor under Siege explores how the influential union persisted in an era when the US labor movement was under attack and seemingly in retreat.

In the face of grave dangers since the 1980s, including threats from corporations, government authorities, law enforcement agents, and even other labor unions, the ILWU has persevered and retained its vibrancy. Offering insight into Big Bob's leadership and a close-up view of how decision-making and policy were carried out to ensure the union's survival, Labor under Siege shows how union officers and rank-and-file members shaped ILWU strategy and furthered the union's legacy of advocating for workers' rights, democracy, and justice.
