Love all the people chipping in despite knowing nothing about us, what we do or who we employ.
Hours are 9-5 but we ask that they're "in" at 5 to so they've got time to get things turned on, put the kettle in, etc. No different to any other job.
Just out of interest, how would you find out if they were "messing about" (ie 10 minutes late) when they're the only person in the office?
And how is being in work on time needless? And don't insinuate that I'm a prat. If you can't provide a solution or at least something constructive then don't bother posting.
In what job can you turn up at 08:59:59 and be fully and functionally working 1 second later?

It takes longer than that to walk through the door and it goes without saying.
