thanks for the above. the spirit of what I'm asking may be misunderstood. its a wonderful company and I would never harm it with a legal case for any monetary sum. Essentially I believe its probably right to compensate me but I'm interested to know if the law would back my opinion. If it wouldn't, then i believe its not right for me to ask - because laws evolve over long periods of detailed examination and argument (as opposed to my personal analysis which is more likely to be flawed).
In answer to questions:
1.The summary from ajapale is correct - except its the legal interpretation alone that interests me.
2. I got a few scratches but i don't care about that.
3. I'm not in a trade union and i've zero interest in ever being in one.
4. Spoke with manager (who is very sympathetic) and HR (who've never seen a case like it before and is looking into it)
To answer Dereko:
1+2.Only trousers damaged but completely non-repairable.
3. Yes - loads of people saw me fall and saw the damage
4. Yes - I told and showed my manager within an hour
To answer Spudz: It was actually a required activity - I'm of a mindset where I'll do anything (as long as not morally incorrect) to help and promote whatever organisation I work for. I do much more than my job description demands (as do many of my colleagues). The request was a required activity but I wouldn't have worn my suit if I had known what it was in advance and we were not made aware - therein perhaps lies the rub.
In summary I just want to know if the law would see my request as a reasonable one - because if it wouldn't, then I consider it unreasonable of me to ask.
