I graduated from college about a year ago, and took a job at a company that I interned with for about a year and a half. Everything was going great until one of my senior level coworkers was promoted to a higher position without them finding coverage for my team. I'm now working long, crazy hours and on projects way advanced for my job description. Others on my team who are paid more with a higher job level weren't given additional work like I was. I'm not sure if I should look for other employment or ask for a raise (which I also have no idea how to go about doing). I generally like my boss and team as people, but the work is getting out of hand and I'm starting to feel a little run down. Any advice?
