You'd be surprised at the amount of evidence required to make a good case. My wife and 3 other women decided to investigate this option and pool legal resources.
We came close to collecting enough evidence, but the lawyers we talked to said we needed either a smoking gun, or more overt documentation to establish a pattern. Most of the outward sexism was verbal or in the form of indirect patterns of employee movement.
At one point we considered secretly taping conversations but it turns out those are illegal in our state, which is too bad as my wife related some cases that sounded like something out of a bad 1940's movie.
