According to BBC reports, Colin Woods lost his appeal after an employment tribunal ruled his employer, Home Delivery Network, had taken a ‘reasonable response' to dismiss him for such ‘serious misconduct'.
The driver was caught in the act last December by a local resident in Kircaldy Scotland and, when his employers searched his vehicle, they found a bottle of what they believed was urine although Woods claimed it was Irn Bru.
The tribunal said: "Such an action is clearly serious misconduct on the part of an employee as well as probably being a criminal offence.
"Any reasonable individual must know that he should not urinate in a public place in broad daylight in a built-up area.
"In the circumstances, the tribunal are satisfied that the company were within the band of reasonable responses in deciding to dismiss Mr Woods."
