That is correct, work visas are restricted, tourist visas however are not required and I am not aware of any such requirement between any two EU member states. I haven't used my passport in years, I use my Romanian ID card whenever I travel in the EU (and it is my understanding that any EU citizen can travel - for business or pleasure - within the EU without visas or even a passport).

I'll add that information shortly - for things like EU citizens travelling in the EU, I try to put a little more information than just "no tourist visa is required".

You also don't need a visa for UK -> Switzerland.

Switzerland is also Schengen so you don't even need a passport to enter from other Schengen members (which unfortunately excludes the UK)
