Freeport-McMoran Corp. Customer Service Issues

I am looking for the contact information for Freeport human resources at corporate. I have reached out to the HR department at the Bagdad site, but haven't received the assistance I need. I believe I am facing retaliation and discrimination. A Bagdad HR senior representative called me a "job hopper," despite my excellent 11 plus-year work history. My former senior supervisor at Bagdad has interfered with my job applications, leading to multiple rejections. I have had to start commuting over three hours a day due to being turned down for over 20 positions in six months. I am seeking help from the corporate office to investigate the unethical and discriminatory practices at the Bagdad mine site. Please do not forward this to the Bagdad mine site.
