Thats an awful lot of stuff to have at work - you just might get something under the temporary removal cover on your own Contents insurance for personal items like clothing or handbags etc - but doubt there would be any cover for items used for your work - bit of a catch 22 sorry ! - more importantly if your employers have no Employers Liability insurance then they are operating illegally. You would have problems if you suffered an injury due to your work - it does happen - even computer operators get repetitive stress problems !
