Apart from US, in which countries:

1. employer is allowed to unilaterally change contract with employee?

2. employer is allowed not to pay for overtime?

3. employer can fire somebody at a whim?

In my country all three are forbidden by law, and I haven't talked about unions yet.

The fact that the law says that something is forbidden, it does not mean that all the companies comply, having something on your side helps you a lot when you fight the company to make them follow the law. Also, my examples are quite clear, but there are always grays.
