Re: Late to the thread, but with an idea...
There's a time limit on there. I think if you make someone redundant then you're not allowed to hire for that position for six months, although I might be well out of date on that. Asking if he knew why the phone bill was so high isn't really anything to do with the supposed redundancy of the job, that just shows a degree of incompetence and lack of proper records in some departments.
