Well, to be fair, Berman firing her for wanting only a part-time gig on DS9 was kind-of a comment on her career decisions, albeit in a rather highschool-ish passive-aggressive way.
"Uppity" may be a bit harsh of a word to use in the case, but there does appear to be a precedent of backlash against women who wish to make such career choices, either by sharing the workload with other shows or asking for greater financial compensation. Claudia Christian was an example already mentioned earlier, as well as Kirstie Alley. Jennifer Lien, IIRC, was just outright screwed out of a job to bring in Seven of Nine. Can't remember the precise conditions under which Gates McFadden and Denise Crosby were cut, but the bridges weren't as obviously vaporized so much as to not allow them to return. I'm sure it's happened to men as well, just probably not quite as frequently or as widely publicized. Hollywood is a tough industry to be in no matter how you slice it. Sometimes you win big during negotiation, sometimes you lose big. It's a gamble.
