Our UK office has been asked to provide employee information to our Head Office in the USA in the Safe Harbour programme. Im happy to provide general employee information but have reservations about providing personal information such as date of birth, NINO and home address. I have managed to pursuade the US office that the NINO is not relevant but they are insisting on the other two. I sent an email to all my employees advsing them that this had been requested and I have been inundated with requests not to send it. Im now caught between the two and Im not sure where I stand.

Has anyone else had a similar situation as I feel under data protection I have a duty to ask their permission but I know it wont go down well with the USA if I with hold information. Do I have any legal grounds not to supply this information.
