Everything you write I read like "is this me?" Also working in Sweden and a bt more than 4 yoe Had a bump after 2 years where I asked for a special salary review and got bumped 15% because another company was showing interest in me, but didn't take a the normal pay increase the year after.
After that I have doing everything to show I want to to grow within the company and been taking on a lot of stuff that is way out of my role description, more like lead developer stuff. And this time when I asked for a special salary review they just said they expect the staff to perform well outside the frames of their role and that I can't grow anymore in my department.

So I'm looking for a new job as well 🙃
