I work in a hospital as a Nurse Educator and I intend to conduct an online survey research study using a quantitative approach. I obviously have an Outlook Group (email) where I could send information to everyone in the department. However, I am only looking into recruiting Registered Nurses for my quantitative research study. I think it is not ethical to approach Managers to advertise my study as this would seem like coercing people. I am not sure if having a gatekeeper who also works in Education would be allowed. Can anyone please advise what is best please?
