I work with a bunch of middle aged children! I love my job but recently I have decided to change some stuff up to improve my analysis (I am in finance) and the accounting people (middle-aged children) hate change. So now the manager in the accounting team has decided he doesn't like me and doesn't want to talk to me. So his direct reports are doing the same. They've made a workplace relationship so hostile right now and it's getting worse each day. My manager supports me 100% but also knows you can't teach an old dog new tricks. So it is what it is - but of recent this accounting manager has started to talk a lot of shit about me in emails that I have changed things and to my customers too! The other day I was so mad - I closed my office door and sat before i said/did something wrong. He's 45 years old and is acting like a 15 year old! This isn't freaking high school - it's a professional organization. Neither my dad or his dad owns it so he needs to get his head out of his @ss and deal with it! So with this I have been hating coming to work. I love my job and company and I don't see myself going anywhere anytime soon. But this "kid" is making me want to move NOW!
