Russia’s Federal Antimonopoly Service has filed antitrust cases against job boards HeadHunter, Superjob, and Rabota.ru.

The FAS said the terms of use for the three job boards’ services contain clauses banning the use of automated recruitment software when working with the firms. The FAS added that, “at the same time, these resources occupy a dominant position in the job search market on the Internet” and “dominate the market of information exchange between jobseekers, employers, and staffing agencies in the Internet.”

The watchdog also found that the firms block users if they use software of third party developers for automated recruitment.

FAS opened the case following a complaint from a developer of an automated recruitment tool and then concluded that the actions of the three recruitment firms may restrict access of businesses offering automated recruitment software to the market of information exchange between jobseekers, employers, and staffing agencies via the Internet.

According to the FAS, the Law on the Protection of Competition prohibits entities that hold a dominant position from creating obstacles to others entering the market.

A spokesperson for HeadHunter said the company will study the claims further before taking a position, but said that the company complies with Russia’s laws, adding that its database of CVs is its own intellectual property.

Meanwhile Rabota.ru said it had not yet received any claims from the FAS. Superjob said it was not aware of the filing and said it would provide the FAS with all necessary information upon request.
