Seeking input or advice. I work for a large corporate company that's acquired multiple different companies under the main one.

A year ago, I moved to one of those acquired companies. I love being a manager and I have a team of 5 of who report to me. They're all incredibly great, driven people. Unfortunately, the culture at the rest of the company is incredibly negative. It's putting me in moods I never thought I could be in. I love the opportunity I have but I don't think it's worth working with the day-to-day aggressive and negative atmosphere. Is there a way to help with bad company culture? Should I not waste my time and look for another manager position that will keep me happy? Ladies, advice??
