I previously worked with lotsa the chancing c#### you describe, many of them (not all!) were Tories and quite happy to see other union members pay out their monthly fees while shamelessly picking up their amended annual salaries due to the pay bargaining of union officials. It was a win-win position for these morons apart from the odd occasion they were confronted by other colleagues re their stance in happily picking up the money and having the "brass neck" to brazenly take the criticism and move on regardless. This has always been one of the huge weaknesses that has existed in the workplace; it is still present today and divides people - straight out of the Tory (aka the selfish, greedy bastards political party) employment manual on the cynical division of working people/employees. IMO one solution to this problem was to force non-union members to negotiate their own pay deals. However, that wasn't possible to achieve anyway because of the anti-trade union laws imposed by the Tory govt thereby ensuring such division while it is a fact that many middle-management to upper-man staff in certain employment sectors did indeed negotiate their own salaries while doing it discreetly. My main point is that this issue has always been a mixed bag of anomalies within the employment sector.
