Pros
Good vacation and sick leave policies. Love the flexible Alternative Work Schedule arrangements (termed AWS). Work is interesting if you like tax.
Cons
(1) Have to spend time covering the toll-free line and talking to taxpayers who just don't meet the tax law requirements but who are desperate and want to argue thinking that they can somehow convince you - like we could waive the requirements or something which we cannot. (2) The work is terribly boring if you are smart. After the realignment in Fall 2014, almost all work is Earned Income Credit related. I am disappointed in how not impressed I am with my co-workers. So, if you are looking to basically never learn, do the same thing and crank out documents related to EIC then this is the place. It is steady employment that can do until the day you die. Difficult for an intellectual to do this job. Have to find learning outside of work. And it seems that people find it threatening when you know a lot.
