Then the employee must have granted the employer a complete and exclusive right to use the copyrighted produces. There is not other solution: otherwise you can extort your company by threatening to leave and revoke all their rights to use your work of the past years. Many types of companies are near impossible without exclusive rights to the fruit of their employees' labour.
This is why in for instance The Netherlands, in every contract, an employer will by default demand all the rights related to work you do in your spare time, if it is related to your profession. And this makes complete sense: in the past, there have been problems with people that loved their job, did some work in the evenings for purely job-related stuff, became disgruntled later and successfully sued to the company for infringement.
