Wonder what the pay's like?
I was speaking to a mate who works for TRL (formerly Transport Research Laboratory), and he was telling me that 'Cone Chuckers' (the people who set out roadworks) are on £40,000pa.
I was kinda tempted by that idea for a while, until I thought about it and realised that it would involve standing in the middle of the M1 at silly times in the morning, in all weathers, surrounded by motorists who had left their brains at home.
