Yeah - imagine it flying over the White House

- In fact, I seem to remember fighter jets scrambling after a pilot accidentally flew his single-engine Cessna into restricted airspace over Washington back when Bush was Pres.
Only in Canada can workers be forced to join a union as a condition of employment, and even if they are not forced to join, they still have to pay full union dues. Even opting out due to religious reasons does not entitle workers to keep their money, it goes instead to a charity of the union's choice See the Rand Formula.
Labour laws need to be changed to protect workers from the voracious appetite of unscrupulous and virtually unaccountable union bosses. Why should their union dues go to political causes they might not agree with ?
