Nokia

• People are nice and helpful.
• It's a good company to start your career as a student.

Pay raises are very small or even zero. So you earn less due to inflation. It makes no sense to me that new hires often earn more than experienced employees.

Your project can be moved to another team or country with very short warning, so you are forced to move to something else (even to a different programming language that you don't know).

I didn't feel impressed by Nokia's approach to work from home. The company refused to fund home office equipment like ergonomic chairs.

People are leaving because new hires get more money than experienced employees.

If you aren't fair, people will not stay.

Because of management and budgeting decisions, Nokia has become an entry-level company for 1-2 years, not a place you want to stay for long.

It will be difficult to repair this image, but noticing your existing employees is a good start.
