Depends on what country you're in. It's illegal here in Australia, but almost universally practised regardless. The law is not in reality available to most people, nor is it by and large adhered to by business except where absolutely necessary (ie. predictably enforced). Every large company I've worked for has broken the law with impunity.

There good cause for "the law" in daily reality (as opposed to "The Law" as an abstract good) not to be held in any esteem by ordinary folk.
