Isn't it a terrible thing when you cannot carry your beloved bag to work. Fortunately being a tutor I don't have to face this, but when I carry my Balenciagas I have to be extra careful to put them away from the little devils with pens in hand. I am more comfortable with my LV bags as they don't get dirty at all and I prefer the DE ones with no vachetta if I have to be totally carefree. But if you have a problem of your bag being taken, then you'd better get a cheaper brand or buy a cheap preowned that you wouldn't care so much for. However, most of the times the inside stuff of the bag is more important so if you didn't want to attract the thief you should just stick to a cheaper brand for work.
