Picking up on a few of the points raised:
- The role is unpaid as this role is suitable for a PPL and it's illegal to pay a PPL to fly
- We don't charge the staff tuggie for their training
- Quite apart from the benefits of having a Silver C, it's also a requirement of our insurers.
Many thanks for the responses I've had. Our e-mail system seems to be ever so slightly up the spout

at the moment, so if you haven't had a response please use a PM.
Flying Dutch - I believe I have responded to you, which suggests our outgoing e-mails aren't working too well. I'll resend tomorrow.
