Ive worked both. Union and Non Union. Biggest problem I had was that my union dues were going to pay arbitrators to handle grievance's that would keep the shitbags from being fired. BA would roll up in a caddi. Every contract we would lose more and more. Lost my pension because I wasnt vested when they took that away. So I became a manager and haven't looked back since. More money, but now I have no union to back me up if I lose my job. And to Jared's point, I do my job well, dont fuck the company and I get raises every year for my hard work.
