Throughout her career, Mijatović has been engaged in media issues across a multitude of disciplines, with substantial experience in Bosnia and Herzegovina, as well as intergovernmental settings. As early as 1998, as one of the founders of the BiH Communications Regulatory Agency, she helped create a legal, regulatory and policy framework for the media in a complex post-war society. She was also involved in setting up a self-regulatory press council and the first free media helpline in Southeast Europe.
In 2007 Mijatović was elected Chair of the European Platform of Regulatory Agencies, the first woman and the first person from a non-EU Member State to hold the post. Prior to that appointment, she chaired the Council of Europe's Group of Specialists on "Freedom of Expression and Information in Times of Crisis". During her chairmanship, the CoE Committee of Ministers adopted a Declaration on the “Protection and promotion of investigative journalism” and issued Guidelines on "protecting freedom of expression and information in times of crisis.” As an expert on media and communications legislation, she has worked in a number of countries. In addition, she has lectured, in her home country and abroad, on various aspects of media freedom and regulation. Since 2000 she has taught media regulation at the Universities of Sarajevo and Banja Luka and, among other teaching positions, has lectured at the Academy for Political Excellence and has served, since 2008, as a permanent lecturer with the jointOSCE / Ministry of Security project on "Media, Security and Hate Crime".
In 2010 Mijatović succeeded Miklós Haraszti as the OSCE Representative on Freedom of the Media. In accordance with the 1997 Directive that established the post, Mijatović aimed to fulfil her mandate as OSCE Representative on Freedom of the Media by observing relevant media developments in OSCE participating States, advocating and promoting full compliance with OSCE principles and commitments concerning freedom of expression and free media, and sending early warnings and implementing rapid responses in cases of non-compliance. In March 2013 she was reappointed for a second three-year term as OSCE RFoM Representative.
