Hi, I have personal experience about this thingy.
If I read correctly, you are a specialist in Navigation Systems, and with a project manager role.
I strongly believe your salary should be over 100kchf per year (gross), without considering bonuses (vary company to company). Sorry to make you sleepless tonight.
I hope other people will not continue to view me as complaining about the Swiss, but this is what happened to me, and to some other foreigner colleagues. We work in IT line, and specialists not available in CH.
(Hence I say "we")
1. We were solicited for the job/role (was told it is urgent)
2. We were given a salary quote (usually a range, and not a number)
3. We were told to resign and pack up and come here asap (with family)
4. We were told, swiss people/company can be trusted
5. We were told we will be paid according to local ranges and that we will live well
6. We resigned and prepared to move
7. We were shown draft contracts (numbers not fixed)
8. After some time, contract is fixed with lower end of range (we were again told this is correct salary scale)
9. We came, met some other people on the job (swiss people with less skills, less certification, less experience, and go home at 5pm everyday)
10. We realised they live in big house, draw a significantly larger salary, but WHO'S complaining, right? Not me.
11. Some of us asked for revision of salary (a few succeeded in getting 100chf or 200chf more per month), others were told it is company policy not to change the salary range "too much"(so that all employees will not be unhappy).
My manager even hinted that "not everyone can work and live in CH" as the reason I should accept the salary discrepancy.
12. Luckily I negotiated for the high end of the range before I came. Others were not so fortunate.
I learned that once you are in that range, it is almost impossible to get out of it, unless you are promoted to next range (which almost never happens, unless one guy above you DIES) Or you move company (and you have to convince your next company you are worth more than the previous salary range).
13. Til today, (5 years on), I had my actual salary AND benefits decreased, due to switching from Expat terms to Local terms.
14. I accept all these, because I like the fresh mountain air, compared to the dirty Asian Haze. And I am making "more" than in Asia, but my spending power is less in price-high CH. I can save more, really (because shopping is a luxury thing here)
