Pros

Good pay, big department and many people to talk to. Good conditions. Overall mostly quite professional.

Cons

IT system slow and very very unreliable. I spent hours of unproductive time just trying to access emails and online training. I also spent a substantial amount of time submitting requests trying to get the IT system fixed, usually to no avail. The IT system was a constant source of frustration, and site-wide it probably totalled millions of dollars in lost productivity.
