Welcome to office politics at bigco! You're upheaving the existing processes and people don't like that. You have to remember that the trade-off for working at a big company is larger scope projects, higher pay, more upward momentum in exchange for working fewer hours, dealing with more bureaucracy, and having a more limited scope role. Most of the people you work with really want 40 hours a week, and you will really want 40 hours a week in 7 months. I can't tell from your original post if you're working 60 or 40 and just being more efficient. If it's the former, stop now. Go home at 5pm, have a beer, enjoy life, and try to repair some of the relationships with your coworkers before they turn into backstabbing assholes. If it's the latter, you might want to slow down the rate of change, or at least change the way your coworkers do their jobs. Change how you work. If you need to change how everyone else works, get buy-off from other people before you impose. Sometimes you need to impose changes, but that burns political capital and goodwill until they can see it's better. (Note, if it's not better, this obviously means you'll never regain the expended social capital) With the exception of your coworkers begrudging your work output, are they still generally cool & interesting people that you can learn from and get along with? Then you should really consider staying. As far as challenging work, you're what, 3 months into the new job? Depending on your boss, he could be holding back some cards so you get a slow exposure to the company. I'd highly suggest talking to him and reconcile what you thought the position was versus what you perceive it is now. He's obviously impressed with you now, so you'll have much more slack to do what you want.
