So I've been working in the company (picking up startup) for 3 years and I am the most senior employee. I see that I am very valuable and I am fair and working hard. I am from Poland, the company is from Belgium. My salary is at least 50% lower than enployees in the origin country. I propose 25% of the rise and I got response with 12% of raise and if I don't accept it then good bye. I tried to negotiate to 20, 17, 15% but nothing. Only I have to tell do I accept it becaude they need to adjust to the situatuation (in the other words – you take it or see ya). I understand the differences in the economics, but really? Is it normal around the companies that they prefer waist more money and time in searching and learning new employee in HR proccess? I just can't understand that.
So the only way to get a good raise is to find another job.
