I drive a company vehicle ( recovery truck ) as part of my duties and as with all of the company vehicles it as a tracker fitted for purposes of theft and or monitoring the location of the truck and myself to see if im in a location or area or if im going to be in that location within a time slot to attend another job, I have no issues about this at all as it makes sense and is cost effective to my company to send the nearest truck to attend a brake down, my niggle is this, my employer as given the log in details of the tracker to one of my co workers who when not engaged in work duties logs in to the tracker on his mobile phone and checks other drivers locations including my own, i have asked him countless times not to do this as i see this as an invasion of my privacy and see no reason for him to know were i am, his answer is always the same ( hes not watching me, hes watching the truck ) and this same answer as been repeated by my employer when ive brought the issue up in front of him although the truck is issued to me and parked at my home address when im off shift and not used by other drivers, i also feel as hes doing this during the shift hes also watching me when hes off shift as my shift ends 2 hours after his but i have no way of proving that its just a feeling, i have also brought it to his attention that im sure its a breach of the Data protection act as the information is in fact being distributed by him having the log in details for the tracker, so the question is, is there any laws on this and can i do something to actually stop my co worker spying on me ? or do i just bite my lip and put up with it,

hi guys, i was witness to a fight outside of work which involved a collegue. i told the police that i didnt see who hit who first(which is the truth) but i suspected that my collegue was hit first because his teeth had been knocked out. now when my boss asked me to give her a statement i wrote that i saw the other man hit my colleague first. its now going to crown court as my collegue is acused of stamping on the other man. can my boss sack me for giving her false account of what happened.
