Copyright law deals with the situation you've mentioned in different ways in different countries. For instance, it is just illegal in Europe to transfer the credit of one's labor (or copyright). In the Americas, however, companies blatantly mention in the `TOCs` that they own rights over employee's all work.

Of course, the extent to which the law is actually applied in Europe depends on the conditions of employment and whether the employees have the time and resources to wage a legal war against their employers.
