I just found out that someone I worked with a couple of jobs ago was promoted to a major leadership role in the organization.
It pisses me off because she was literally the most inept person I've ever worked with. She started a year after me and was very nearly fired after her probationary period, which is unheard of (they wound up doubling it to give her another chance). She was so bad at her job that we had to reshuffle responsibilities because she couldn't handle the same workload as the rest of us. Our position required working with other people in our department to get them information/analysis, and the people she dealt with used to come to me and complain because her work was so shoddy. About six months ago, she moved laterally to another department in the organization, and I got a text from my former boss joking about how glad he was to be rid of her. In fact, I remember when my former boss promoted into his position (we were at the same level prior and became friends), and the biggest thing he dreaded about the promotion was managing her.
The list goes on and on...
I just don't understand how someone so terrible at their job makes a huge jump while the talented people have to pay their dues.
