What you're talking about is more like mainstream Syndicalism. Corporatists don't like worker's unions because they're easily infiltrated by Communists, and don't do much other than hurt the economy and steal worker's wages to pay the salaries of corrupt union bosses.

We support right to work legislation, but believe every worker should be a member of a government-sponsored guild for their trade. Corporatism would look more like the Director's Guild, which has done a pretty good job at self-regulating the film industry, but it's been infiltrated by Communists — but to be fair, the entire country's been infiltrated, so it would be unfair to single them out.
