"make it so that you really don't want to work for them any longer"
Constructive dismissal is likewise illegal where I am. It's not common, but it happens often enough that most people will have heard of someone. The employee is entitled to cease work immediately AND receive compensation at tribunal for being illegally terminated. Media reporting of these incidents is usually hugely negative, enough to make avoiding them a priority if your company's reputation is of any importance.
Obviously if both the employer and employee are no longer happy it will usually be possible to agree some mutually acceptable way to end the relationship, and the courts won't interfere with that.
