The modern Royal Air force can be a difficult place to work. The management will always try to get more out of you than can actually be achieved. We are stretched further now, around the world, with fewer resources. However, you learn great skills, work with some cutting edge technology and can gain lots of qualifications, not to mention life-long friends.
See the world and have a secure, well paid job.
Management are always pushing so they look good and get promoted.
