What to do about Rude gossiping co-workers?

I recently accepted a job as a Self Storage Manager with one of my previous employers competitors.I left my last job because they couldn't accommodate my pay request. The facility I ran was #1 in the area and I am still working in that same area just for a different employer. needless to say the sign-on bonus was nice. BUT here is the problem, my employer has several facilities and I am being trained by ppl who were once my Competition. There is a negative vibe in the air. I HAVE overheard them gossip about everything from what i'm being paid to them being jealous that i have weekends off and other perks I received for accepting this job.At first I could have cared less but it's interfering with my learning of my new job.There are things I believe they are delibratly not teaching me to see me fail. I just can't believe the instant negativity Ive gotten from ppl I barely know. All they've known about me is that I ran the largest, most profitable store in the area, and youd think that they would be happy to have someone as productive as I am on the team.
