Now, I distinctly remember, when I first started work here, bringing in my passport, having the group secretary make copies of both of those things, both of us signing them, and delivering them to HR. So as far as I can tell, they bloody lost those copies.
Perhaps I shouldn't be too surprised given the propensity of British administrators for misplacing vast quantities of sensitive information.
Should I comply with this request?
Just do it, don't make a fuss.
Yes, but you should write "ATTN: THE INCOMPETENT GITS" before your signature.
Refuse to comply until they tell you what happened to the previous copies.
Set the building on fire.
