I've been working as a software developer in this company based in Germany. For several months I've noticed this particular behaviour from my manager that may affect my motivation in the future.
In team meetings when I offer a solution to a problem, the idea is often rejected almost immediately whereas another solution coming from usually one of my colleagues is automatically accepted. After I'd noticed this pattern, I started discussing my idea with this colleague and then presented it at the meeting saying "I've already talked with XXXX about this and we agree to do it like this..." And 100% the idea is implemented.
We work in a very cooperative (non competitive driven) environment and the results suit my main goal that is doing things the best way. But if I start thinking about this issue in a more personal way I know that this is not very motivating.
The question is, should I address my manager directly about this issue? Or should I keep using my strategy in benefit of the team stability?
