Work Getting Worse!

Well every day for the past 2 years I was able to bring in my laptop and listen to MP3s on it. Well as of today I got a great e-mail stating that no employoees can bring in thier laptops. Well I am on the second shift and I have the 2nd highest call stats in the center. This has shown to not impact me before.. why now. I know of the security violations. I dont' have it connected to the network and I have Wireless Dissabled. So I am not sure where the problem is. The reason I am even in this possition is the freedoms it gives while I am at work so it doesn't feel like I am at work. Hmm.. time to find a job that doesn't feel like a job. (wich is uhh impossible now a days.)
