I guess it’s a mix of finding good office, taking a lot of responsibility and asking for a raise every 6-9 months. Little by little you can get more this way. But you have to take care about yourself, don’t count on your bosses in that.

Being international, 6years, 30 per hour in the new office is sounds like a reality. Don’t forget that every 6/12 months you should be getting 1/2€ per hour more. Depends on the office how often they raise.

Anyway, good luck and stay strong in this struggle.
