I believe that the consultant was in violation of an NDA or CDA, especially if this was not agreed upon by the other company he used to work with. I think this is also why it is necessary for companies to work directly with attorneys in such matters to protect the company from any legal actions that can occur or to file legal actions against consultants or parties who are not in compliance with certain contracts or agreements. Moreover, it is also important for the manager and employees of the company to understand the rules to the binding agreements made. Because your manager knew that the consultant was in violation of the rules, he was able to recognize this and use the company’s own template in order to avoid any problems with NDA/CDA violations – even without asking an attorney.
