NT thinking and DBS Identity Checks

My employer insists on DBS checks every three years (I work for a company which works with vulnerable children and adults).

As part of this check we have to provide id, a passport or driving licence and another one sort of id with an address.

I don't really think this has been thought through though.  We can put the manager down to verify our identity when applying for a passport.  When we have done this, the manager asks to see our passports when getting the DBS check done - some sort of circular thinking, as she is the one who verified who I was anyway!!!!

I also wonder why it is necessary to confirm identity documents every three years anyway.  I don't think I have been replaced with a clone, and if I had the clone would no doubt be able to produce some documents having gone to the trouble of looking like me.  The manager still knows who I am, they had to have documents to start with and have my picture on file for my work id card.  It would make more sense if this was done at the start of work with a company and on subsequent occasions no further id was required as the manager would then verify identity on the application.  It is not as if the DBS check has a photo anyway..  All that should be required is a verification of address by bank statement/gas bill/council bill.

So annoying .....!
