Well, Sandy, you've probably got all these, but as "concise histories" they are in the same league as Brecher and, as each one (Brecher included) leaves in and leaves out certain things according to their point of view, all together they are very informative. In my favorite order of importance:

"The Labor Wars," Sidney Lens

"100 Years of Labor in the USA," Daniel Guerin

"History of the American Working Class," Anthony Bimba (only goes up to 1936 and is not easy to find)

"Labor's Untold Story," Boyer & Morais, commissioned by United Electrial workers' union
