Wherever I see organise payment by Western Union I think of the Shipping Payment scam. This is where an individual tries to order goods from a company agreeing to pay by credit card (Stolen). He agrees to pay all expenses on this card, however he wishes his shipping company (this is a non existing shipping company very closely named to a large shipping Company) to be paid by yourself (company). The payment is to be with a Western Union Cheque and sent to the sucker who has applied for the above job. It is then his responsibilty to pay into the organisations bank account the shipping cost less his 10%. By the time you realise the scam as a result of bounced credit card you have lost the chance of chasing the Western Union Cheque.
The sucker taking these cheques no doubt would eventually have a lot of questions to answer, but I'm sure that the end reciever of the monies would be untracable.
