Well I'm chuffed to bits that I've brought y'all a bit of a grin. You are absolutely right felling TPO'd trees is absolutely a gazillion miles away from a heinous crime such as rape. And, I was not trying to compare the two on an equal level.
My point was, that the OP was getting a bit of stick for "grassing", and I just felt that if we are not prepared to speak out when we see wrong doing, where do you draw the line.
The fictitious examples I used to illustrate this point were deliberately put at the "extreme" end of the scale to try and counter other posters early responses that somehow, the OP's actions of trying clarify the TPO situation were more reprehensible than the possible actions of a tree gang working on a group of trees without having done the necessary checks with the LA.
The OP IMO has done the right thing by querying the situation with the LA. And I didn't feel that they should be labelled as a grass for doing so.
And yes Huck, whilst is not a hobby that consumes my every waking moment when I'm not up a tree, I have reported people for littering and fly tipping which I have directly witnessed, having first confronted them to remedy their antisocial behaviour. I don't see why I have live is someone elses filth.
I've also confronted and reported someone for using drugs whilst on the job, similarly I've reported someone for stealing fuel/equipment from a mutual employer.
As another example: You've got two guys working for you, one's nicking bits of your kit and the other one is dead straight and honest. The thief is costing you time, money & resources and you can't figure out why the books don't balance. Eventually Mr.Honest tells you about the nefarious activities of Mr.Thief. Do you then sack Mr.Honest for being a "grass" and reward Mr.Thief for keeping his mouth shut?
By deliberately using a few extreme examples, I was trying to emphasise that people who report wrongdoing should not be labelled as a grass or somehow be seen as a more lowlier specimen than the wrongdoer!
