The festive period is often a time of reflection. As December rolls around, we're sometimes haunted by the ghosts of Christmasses past. Of years when the office was festooned with tinsel and the wistful tones of Mariah Carey echoed around the departmental kitchen. This can go either way, of course. You might feel a touch of nostalgia for the years when reindeer sweaters were de rigueur at your Friday morning accounts meeting. You may, on the other hand, shudder at the memory of an office Christmas lunch of lukewarm turkey and soggy sprouts. Either way, this time of year has a habit of focussing the mind on the issue of RTO - the "Return To The Office".
