That's a nice thing in Switzerland, even if developed with company resources, only what you're being asked to do belongs to the company.
Things that are done in the course of employment (but aren't part of the contractual obligations) would often need to be disclosed and the company could license it. IP would typically still be owned by the employee.
Obviously things done outside of work would be even more clearly owned by the employee.
I wonder if any other country has a similar system.

Many states in the United States have limitations on IP assignment that protect against overly broad contracts.
Employers write their contracts as broadly as possible with the understanding that state limitations will limit any overly broad claims.
California (where Google is headquartered) is one such state with IP assignment limitations, though I'm not sure how much of that was in place when this article was written nearly 3 decades ago.
