Building on the success of the AWO, the IWW's LWIU used similar tactics to organize lumberjacks and other timber workers, both in the Deep South and the Pacific Northwest of the United States and Canada, between 1917 and 1924.
The IWW lumber strike of 1917 led to the eight-hour day and vastly improved working conditions in the Pacific Northwest.
Even though mid-century historians would give credit to the US Government and "forward thinking lumber magnates" for agreeing to such reforms, an IWW strike forced these concessions.
[2] The absence of an existing industrial union structure within the Canadian OBU caused the LWIU to pull out its 20,000 members.
The modern IWW website describes an offshoot led by James Rowan of the LWIU, who invoked the E-P (Emergency Program.)
