It's been 8 months that I'm hired, I'm backfill of a promoted guy who is supposed to mentor me.
I have more than 10 years experience but when they were interviewing me I told them that I'm new to the applications they use and they were okay with that. My supervisor (who is another guy) recently told me he was satisfied with how fast I learned everything with their system; according to my mentor's comments and another guy's who sometimes mentor me as well.
The problem is that my main mentor doesn't assign me serious tasks and whenever I ask him for it he just tries to keep me busy with ridiculous, unnecessary, and sometimes fake tasks.
I have talked to my supervisor a few times that I'm idle most of the time and need to be assigned more tasks to be able to learn more and get experienced and he has always asked me to coordinate with those two guys but nothing has changed so far.
I don't know how to resolve this issue since neither talking to my mentor nor my supervisor has helped so far. Any suggestion would be appreciated.
