:::::It may not be uncommon, but is often not a good idea to have one, as the essay WP:CRITS explains.  It does talk about having a short summary that links to the dedicated criticism article, as is the case here, and I think that the current version is fair and adequately concise.  However, I still believe it has the potential to easily become a coatrack, and we already have criticism spread around in this article, like Employee and labor relations section, which too links to the criticism article.  Should that, et al, at least be consolidated into the criticism section here?
