StGallen bro from above. The numbers are legit. Again, it's what we get across several faculties in the country.
I don't think this is true. New AP make about 120k. So 80k for a PhD student seems way to high. We pay about 3500 a month (13 months contract) for TAs.
In Switzerland the pay for a 100% PhD position is around 80k CHF. Most people get 50%-60% initially depending on school and department (so about 40-50k). You may get more % by RAing or because your advisor likes you.
