First, ask a good lawyer, don't trust anything on the open internet. The law and jurisprudence in each country covers what (intellectual property or other rights) belongs to your employer and if you are allowed to work on anything outside of an employment contract.

Sometimes a well crafted non-compete, non-disclosure or employment contract can override a law, but that is never certain. Be especially careful with preparations for starting a business or defining a business idea. So what you can do as an employee is decided by a judge and nothing else is legally sure.
