A member of staff filled the ban out with £20 of petrol and £50 of diesel would you make them pay the cost of draining the tank or would you forego the costs?
First time? Good worker? No discipline record? Let it go this time.
Mistakes happen and this is quite a common occurence. Make sure he knows though how close he came to being charged for it.
(If he is not so good a worker, only you know how to handle it)
Is it clearly marked in the van, on the van by the fuel cap, on the keyfob that this vehicle is diesel?
If not get it marked up and then issue a memo to all staff, that should this happen again, they will be responsible for related costs of correction and a verbal warning
