You need to back up your claim with evidence. In order to establish a union, you'll need at least 30% of the workers signing a petition. Would you sign such a petition if your incompetent colleague put it forward to you in the hope of protecting their job? Honestly, your scenario is far-fetched.
In order to establish a union, you may need 30%, but how much do you need to TRY to establish a union? After all, they didn't succeed? How many of their coworkers signed?
Besides, there may be many people who think having a union is always a good idea, so they would sign without thinking about it much.

Why do you, what's the reasoning behind that kind of law? And to whom do they petition - does the company have to agree, or rather, does the employer have the right to forbid employees from forming agreements between themselves? It sounds counterintuitive when you only need 1 person to start a company, or 2 people to have a contract, and when employers have no other control over who employees meet with and little control over how employees spend money (e.g. 'work dress code').
I don't know the answer to your questions, but it is simply the law unless the employer voluntarily recognizes the union. Obviously employers don't have much incentive for doing so.
