<prompt> Human: Hey guys,So I work in the engineeringdesign industry, my work is project based. Our clients pay us fixed fees for our work. I wont go into what we do to maintain anonymity. Ive been here about three years, I started here as a college grad, and find my progression with the company satisfactory. Anyways, recently we hired this new guy named Danny fake name. Danny comes from another company that does the same thing, and when he was hired, I was told by my supervisor that he had 2 years of experience. He was also hired on as the same position as me. With this knowledge, I was ecstatic to have an experienced teammate that could instantly hop onto projects and lend a hand.Right after Dannys first week, our direct supervisor goes on an extended vacation 2 months long, and Im left to train Danny alone and with the help of some other, slightly less experienced co-workers - I have a fairly young office. Im also left in charge of several projects that my supervisor needed someone to keep an eye on and manage in the interim.After a couple of weeks, I start to notice that Danny isnt really up to speed on the day-to-day tasks of our job position. Initially, I thought he was at or near my experience level so I would speak to him as such. But then, I started to slowly realize he had no clue what I was talking about. Thats okay, maybe hes just used to different workflows, different office jargon, etc. So I became more patient, and pretty much started to train him as a Day-1 College Grad. He became receptive to this, and started to pick things up. However, he wasnt picking things up like hes done it before and just needed to brush off some rust. It was like he was learning everything for the first time. Even concepts or processes that I had learned and have been doing since I was in my first few months in the industry.So, back to the managerial tasks. As the interim manager, Im left in charge to manage and review timesheets from time to time. Just as a way to ensure were all working efficiently and billing to the correct projects. I come across Dannys hours that he charged to one of my projects. It had taken Danny about 12 hours to complete a task that wouldve taken me 2 hours. I took the loss on hours in order to take my time with him and provide him the training he obviously needs. It wasnt until I checked what his hourly rate was, and it was 15 higher than mine.THIS GUY IS COSTING 15 MORE PER HOUR TO USE ON A PROJECT THAN I AM, AND IM THE ONE TAKING MY TIME BABY-TRAINING HIM. I was pretty upset when I discovered this. I had been working late around 9pm when I discovered this, and immediately after, I had to leave the office. I felt sick to my stomach hurt. Heres a few other factors:1 Danny has told me that his 2 years at his previous company, time was split between what we do now engineering design and another unrelated field. Because of this, I believe that he REALLY only has around 6 months of experience. Which would make so much more sense in how he approaches tasks.2 About a year ago, I was offered a position with another company for significantly more pay. I turned it down. The reason was, my supervisor had convinced me that culture money, and that the company that had offered me wasnt a good place to work he knew people there. He told me that the money would come, and so I stayed. In the year since, Ive gotten a raise, but still make less than that initial offer.3 About a month ago, I had asked for a promotion at a mid-year performance review because my responsibilities matched with the job description of the position I wanted that was found on our company website. Its the same position, just a higher level, I was denied. The reason was, even though I am handling all the responsibilities of the description, I needed to do them for a longer period of time before I could get the position. This one was bullshit to me. To me, a job description are duties that you fulfill. Which I am doing. I dont believe they are duties that you necessarily need to do for a specific amount of time unless explicitly stated in the description.Right now, Im not sure what to do. Last month, I was denied the promotion which wouldve given me a raise. My supervisors boss was the one who denied me. I work with both my supervisor and his boss fairly regularly so I have a working relationship with both. I want to approach them with the question: Why is this guy more expensive than me on our project billing system? But, I also dont want to rock the boat.Need your advice, Reddit.  <response>: Simple, its time to find a new job. Its obvious your current employer has no intention of paying you what you feel you are worth and youre not happy about that. If you choose to stay your unhappiness will continue to build until you likely blow up at work and are escorted off property.
