Can UK Post-Study Work Visa Help Work in Schengen Zone?

No, a UK Post Study Work (PSW) visa (Graduate Route) does not allow you to work in the Schengen Zone. You would need a separate work visa or permit from the specific Schengen country where you want to work. However, you can travel to the Schengen Area for short stays (up to 90 days in 180 days) as a tourist, depending on your nationality.
