Crowdsourcing Code of Conduct - Ombuds Office

If you think you have been treated unfairly on one of the platforms that have signed the Crowdsourcing Code of Conduct, you can submit a complaint to the Ombuds Office. The Ombuds Office is a mediator between crowdsourcing platforms and crowdworkers. The members of the Ombuds Office seek to find fair solutions to disagreements by consensus.For the Ombuds Office to consider a case, the following conditions must be met:

  1. The platform in question must have signed the Crowdsourcing Code of Conduct.
  2. You have a concrete complaint, for example about money or procedures on the platform.
  3. You have already tried to discuss the matter directly with the platform; however, this has not led to a solution.

Please briefly describe your complaint using the form below. (Please observe any non-disclosure agreements to which you may have agreed, for example with respect to project data.) This information will be sent to the administration of the Ombuds Office, which is operated by the German trade union IG Metall. The information will be kept confidential and will only be used to mediate the case.
