There is a bigger picture in which employers intermediate between producers and consumers. As a consumer, you are free to shop around. You bought a Ford, but perhaps next time you buy a Honda. If the government is really serious about saying that Ford cannot lay off workers, the government has to help. For example, by introducing a tax on importing Hondas.

In the big picture, your job security as a producer trades-off against your right to be a disloyal consumer.
