companies have the right to escort you out of the building the moment your employment is terminated, for security reasons and so you do not cause damage, upset or offence as a result of being let go. it is not personal and you just have to get on with it - if you wish to contact people to say goodbye, you will have to do that on your own time. as for your reputation, you will have been given reasons why your employment ended and as long as you haven't been fired or disciplined, there is no negative stain on your employment record. it may have come as a shock, and you may have been told/hinted at something being different by someone, but within a probation period, employers can terminate you for all sorts of valid reasons. you will have to suck this one up to experience, dust yourself down and get job hunting asap......any gaps in your employment history will be more damaging than a probation period ending. it happened to me, my husband has experienced this too - it is just one of those things.
