I think that it is fundamental to homo sapiens that some will exploit others - therefore I believe that trades unions are very important (I would like to say essential) for civilised societies in which corruption is low.
Not when that union is BASSA, who in my opinion manipulate and exploit their members to the extreme and are clinging on to their positions, being paid handsomely for doing so, despite have absolutely NO right to do so other than a show of hands from the more rabid bunch of Bedfont berks.
