Some but not all of the authors are US Government employees or part of a work made for hire. Can I use the copyright form?

Where one or more of the Named Authors are an employee of the US Government and one or more of the Named Authors do not work for the US Government, both an authorised signatory of the US Government (“US Government Signatory”) and one of the other authors should sign the agreement.  In this instance, please email the relevant journal team who will provide you with the appropriate form.
