Storage & Prioritisation
Well, thanks everyone for the responses. It looks to be a universal problem and I think it's going to continue to be a problem!
Interestingly we've just moved out of an area where we had a bench-room/shelving with labelled boxes, etc. and that office space wasn't much better.
You're right though, I'm not reviewing the team on how tidy they are, I review them on how quickly they resolve calls and how many they resolve so make the place tidy is going to come low down on their list of priorities.
I think I'm going to do something along the lines of photographs and see what happens! And maybe give everyone an hour slot each week where they do nothing but tidy up.
