CATSA...with all due respect. In the US, federal employees CAN join a union. However, they are prohibited from going on strike, they are prohibited from engaging in collective bargaining, and the gov't can release employees at any time when it becomes "advantagious to the gov't" to do so. Since all of the above are written in law, and a union is solely there for collective bargaining, protecting jobs, and striking to get their way, what can a union really do for the TSA? The answer is NOTHING. Remember, the air traffic controllers were unionized, when their union threatened a strike, the gov't waited. When they did strike, ALL of them were fired, over 12,000, and not ONE of them ever worked as an ATC again. That shows the power that a union can have for federal workers.....none. I personally think that it should be that way. The gov't is mandated by the MAJORITY to perform it's duties. It cannot be held up by a FEW who want to wrangle something out of it and use a strike to make their point. No sir, the TSA does NOT need a union, especially since it will only be a toothless tiger.
