Hi I am talking GDPR and Data Protection Act 2018.

Can an organisation in the UK have its sales staff wearing name tags/badges with the employees' full name displayed on them? Thanks

Good question. It appears "data" extends to the printed data so name tags with full name may be a problem. That is, if the employee wants to share, it would be fine. But if the employer forces this badge to be in plain sight, my bet is it's a problem.

Public servants however will get treated differently. A police officer for example might not have their full name but their last name and a badge number.

So much to read on the web about this but it would be best to ask those that set the rules.

"It is likely to be most appropriate where you use people’s data in ways they would reasonably expect and which have a minimal privacy impact, or where there is a compelling justification for the processing."

In most cases, therefore, it would likely be seen as 'reasonable' for full names to be on staff ID badges...
