Is NOBODY wrong in the post ? POST : When I started my job, I honestly loved it. Since then, my manager's boss got fired which caused a chain of events and led to a major management change. My manager no longer had any under him and our small team of 4 in a large company got broken into two smaller teams of 2 under different managers. My close co-worker and I got placed under one of those "professional managers" who don't really know what you do and my ex-manager and his co-worker got placed under another new manager they promoted from an overseas office and moved to our location. 

Ex-manager quickly quit for obvious reasons (losing his position) and his co-worker stuck up with it a little longer but eventually got fed up with and left. This left an odd team dynamic as it left two people under the management of two people. I'm sure it doesn't take a professional to realize how this is a terrible idea. The new overseas manager wanted to replace his team so he started looking for new hires. My co-worker already did everything in the job description for this role since we've had to fill in, he just didn't have the title or pay increase. Many people were shocked that he wasn't immediately offered the job and that they were even considering an outside hire. (I'd like to note here that he and I were doing just fine with the two of us and had someone helping us with more trivial day to day tasks)

Managers told him that he wouldn't be getting the role and they hired someone from outside the company. This upset him... a lot... putting it lightly. He was essentially denied the title and pay for the work he's already doing. 

Today the new guy started. His manager is on a business trip at his old office, so my manager has been handling his start. Right off the bat I knew he wasn't a good fit. The new guy is easily in his 50s and very overweight. Now before someone accuses me of ageism and body shaming, my job often consists of crawling under tables, climbing up ladders and carrying heavy-ish equipment when installing new technology. I don't think I'm wrong to assume he will not be helpful in these areas. I tried to keep an open mind though and talk with him for a while. When trying to show him some of our job or have him shadow me while working, he would be constantly talking over me and try to piggy back on what I was saying. You know, those people who try to finish your sentences to try to prove they already know what you're saying? The final straw is when I got called to troubleshoot something, he met me there. While I was assessing the issue, he starts telling me what to do. I just said, "I know" and walked away. The worst part is that most of what he was saying was wrong.

As I said, his boss who is indirectly also mine is out of town and is expecting me and my co-worker to train. WIBTA if I told him no? I also don't want my job on the line.
