Pros
Good holiday allowance - 25 days, plus the office is closed between Christmas and New Year
Flexible Working - you can work 8-4.30, 8.30-5, 9-5.30, 9.30-6, or 10-6.30.
Lots of different clients to work on, so no two days are ever the same.
Beer o clock on a Friday
Line manager is approachable, but doesn't sit over my shoulder.
Little extras, such as snacks, drinks, yoga in the morning.
Opportunities to improve yourself.
Friendly directors - easy to speak to, and not on a power trip.
Very good if you've had an illness or a problem, to support you/give you time off that you need,
Cons
Some people with the word 'manager' in their title like to look down at people they perceive to be 'below' them.
Not always enough support on big projects.
