Sorry, you just seem childish to me; nothing in your reply to me has changed my mind.

He said something that sounded like "I don't care" probably because he doesn't.

He doesn't have to, either. It isn't his job to manage your feelings, he manages the people that work for your company.

>I believe that I am the one that is not being taken seriously even though I can be on almost every position and I am being used.

Most people feel that way, which is why that other commenter accused you of main character syndrome. I'd love for my employer to give me choicier assignments and take me more seriously than they do. But that shit is earned, not entitled. The sooner you accept that, the happier you will be.

And yes you are being used, that's how employment works. The exchange is your time for whatever paid compensation you and your employer agreed to. As long as the employer is paying you, they get to use you for the time that's on your contract.

Unless you have legitimate medical reasons for not doing a task, any request you make for a different task is just that - a request; one they're entitled to decline.

Your only other option is to quit and maybe you can find a job that suits you, but you're being silly with all your moaning.
