Ethical considerations arise when individuals who were contracted and paid to conduct a research study and write it up for publication, are denied authorship on a scholarly publication on the grounds that their work was contracted and paid for. Each of the various stakeholders should be considered. Researchers need to make sure that the contract recognizes their intellectual contribution and their right to be named as authors if and when the contracted study is published. If authorship disputes of published works arise, journal editors should have mechanisms in place for addressing such disputes. They should be able to see the contract and have all disputing parties agree to any changes in authorship. If the dispute cannot be resolved, the manuscript should be retracted. Contractors should develop a publication plan and include in the contract stipulations ensuring transparent and unambiguous authorship on any publication ensuing from contracted work. The International Committee of Medical Journal Editors and the Committee for Publication Ethics should update their guidance for authors to include advice regarding researchers involved in contracted work and how to resolve an authorship disputes around it.
