Hey Gang!
This is a fun history post. I think an important question that will answer the question above is "has the IWW recovered before?"
Here is a table on IWW Membership numbers:
So a few important things to consider:
-The IWW has more members now than it did when it did during some of its more famous strike like McKees Rocks.
-The IWW also has substantially more members than it did when it had a functioning union with thousands of members in the Cleveland Shops.
-The IWW also has about as many members as it did right before things took off in the late 'teens.
-The IWW also has the most members it has had since the late 20's.
From this I think we can safely say the IWW is doing better than it has in a long time. It arguably has recovered a bit. But in all honesty the IWW is doing pretty well.
