The same sort of people who throw stones at paediatricians' windows after a kiddy-fiddling story are running the union Unison, it seems.
At school, our sixth-form boarding house was flanked by a pair of superb Monkey Puzzle trees, so named because the horizontal arrangement of branches would tax the abilities of even the most agile simian to climb. Unison would have us believe they were so-called because they were a barrier to black people. You see, in Unison's thick as a brick collective mind, monkey = black person. This is institutional racism at its very worst. Most normal, balanced non-racist people wouldn't even think of linking the two - but the analogy is so deeply buried in Unison's conscience they reckon everyone else must think it, too.
So when three of their own officials accused the union executive of being like the three wise monkeys - a simian simile from Buddhist folklore - they were immediately accused of calling Clytus Williams, the black chairman, a monkey.
You'd need a heart of stone not to laugh.
