If you want to learn about Wobblies, you can always ask them first hand. /r/IWW isn't the most active subreddit around, but it might be a good idea to stop over there and see if you can get additional resources from them.

The best summary I can give you that isn't Wikipedia and that obeys the 20-year rule for /r/askhistorians:

In the late 19th century, the combined problems of monopolies and company towns were pushing wages and safety down to the point where people were dying in unacceptable numbers, and the basic idea caught on that the way to oppose the power of money was to organize workers to stick up for each other, so they can't be pitted against each other to see who will accept the lowest wage and the least safe working conditions. But, when this idea was relatively new and just catching on, that begs the question: organize them how? There were three models, some mix of which continues to the present day:

• Organize by company: All workers in a company form a union, and vote among themselves as to what wages and conditions they want for each worker in the company, then present that as demands to management. The problem: non-union companies enjoy a price advantage, force union companies out of business.

• Organize by industry: All workers in an industry form a union, and negotiate a standard contract with all the company owners in that industry. The problem: companies trick the different professions within the company into fighting each other over who deserves more.

• Organize by job category: All workers in a single trade agree to set a fixed price per hour, and mandatory working conditions, for any worker who does what they do at each specified skill level: no matter what company you are, it costs you $x per hour for a skilled machinist or $y per hour for an entry-level clerk or whatever, keeping companies from benefiting from lowering wages. The problem: nothing protects workers from investors and banks simply taking their money to non-union countries, and pitting countries against each other in a race to the bottom for wages and working conditions.

Big Bill Haywood was the most famous of the labor philosophers arguing that the only thing that would work was One Big Union: an international standards organization that set standard wages and standard working conditions, world-wide, for each category of job at each skill level, with leaders and negotiators elected in global elections in which every non-supervisory employee can vote, and nobody else.

In 1911, during the Mexican Civil War, unemployed IWW volunteers fought on the anarcho-socialist side, and briefly conquered Baja California, which so scared the US government that the US Department of Justice and other law enforcement agencies declared the IWW to be Public Enemy Number One, and spent the next several years framing every public figure in the IWW for murder and/or acts of terrorism. By the end of that campaign, there wasn't much left of the IWW as an organizing force. There were (and still are) people writing pro-IWW articles, but there isn't much left of the IWW as a union.

I don't have a good book on Haywood (and could use one), but there's an exceptional, fun, and extremely well researched book about Joe Hill and the Wobblies: William Adler, The Man Who Never Died.
