Pros
Pay is ok if you are willing to work the shifts, the pension scheme although hacked to pieces is still one of the better ones out there. The job secure to a degree, but will always depend on the current government. You can always look to do more outside of your main duties but recognition and reward for this effort is lacking.
Cons
Shifts can be tough. Used to be a family friendly organisation which it no longer is. Even though you have a row of days off (3-4 depending on roster) it will start feeling like you never get away. Continued changes, no stability or consistency for staff has caused large parts of the workforce to become unmotivated and upset.
