Is AUTHOR wrong in the post ? POST : This is office/career related, but I feel like jerk about it and do feel that this belongs to this sub..

So I joined this huge corporate as a software dev role, with high expectations and excitement. The role was a mismatch, and I was immediately disappointed after joining. I spoke with my immediate manager about it and he said he’d do his best to change my role.

And this escalated to my unit head and he also told me the same. Fast forward a month later, we have a new up and coming, very prestigious software to be developed and everyone in the team looked forward to switching to that team. The unit head called me up and told me I’m going to be the first one to be drafted to that team - meaning he very well kept his word. He mentioned that it’s a litmus test for our whole unit, as the company is pouring investments for this “market shaker” product and he needs totally committed people, to which I responded that I’m up for it.

The catch is - the product is into a new technology and a new language- which I’m not right now interested to switch. And I got several exciting offers from startups as well which I’m considering.

When my boss spoke with me, I had given my word that I’m happy to be moved to the new product- I couldn’t tell him that I have other offers in my hand.

So AITA if I go tomorrow and hit him with a resignation?
