We had a discussion of employee email address formatting and how to handle collisions in a workplace that hires many, many immigrants. One idea that came to my mind (but wasn't voiced for obvious scope/feasibility concerns) is to do firstname+nickname+lastname so [email protected] displayed as John "Brickman" Smith then during the onboarding process users can select from a list of approved and not-yet-assigned nicknames (I imagine a webpage with a search bar and a "regenerate" button then it shows a list of 10 or 20 nicknames they can select from) and pick something that they like and thinks fits them. It would add some whimsy and worker empowerment but also still prevents interesting situations like someone selecting an inappropriate nickname
