5000€ BEFORE tax and social deductions is very weak indeed. And Munich/Bavaria is one of the most expensive regions in Germany. You need to live with Mom and Paps or somewhere in the middle of nowhere on that, especially with a family.
Always though my employer is cheap and greedy, but even they beat this offer. Should be hard to find this DEC's.
Sad how salaries in this responsible profession went downhill over the past 20 years. And then people wonder why so many run to the ME carriers...
