Timber company boss Jon Walker has been fined £15,000 after a worker was injured.
Employee James Abrahams was walking alongside a forklift truck to steady a pallet of fencing at the company's base in Mansfield Lane, Calverton, when the accident happened.
According to the Heath and Safety Executive, he was run over by the truck.
Mr Abrahams, 21, of Calverton, spent 12 days in hospital and was unable to work for a number of months after the accident on July 30, 2012.
He suffered leg fractures, broken and dislocated toes and deep grazing, said the HSE.
At Nottingham Magistrates' Court, guilty pleas were entered on behalf of the company to two breaches of the Health and Safety at Work Act 1974.
District Judge Tim Devas fined company director Mr Walker £10,000, after he failed to ensure the health, safety and welfare of all employees, including Mr Abrahams, when transporting pallets of chestnut pales through the yard.
An additional £5,000 fine was issued on the second charge – where he failed to make a suitable and sufficient assessment of the health and safety risks which employees were exposed to in relation to the pallets.
Costs of £9,850 were ordered to be paid and a £120 victim surcharge at the hearing on Friday, August 1.
Judge Devas said: "The aggravating features in this case that I have looked at are: the obvious risk that this activity caused and the fact that this was not an isolated incident.
"There was no proper risk assessment, there appears to be a lack of training."
He also took into account the age of Mr Abrahams and that his injury appeared to have no long-lasting physical effect but appeared to have impacted psychologically.
Graham Hills, for the HSE, said Mr Abrahams resigned from his job on January 21 last year due to anxiety and nervousness.
"Psychologically he doesn't want to work with vehicles etc, etc."
Simon Antrobus, mitigating, told the judge: "He [Mr Walker] wants me to say at the outset in public that James Abrahams was a very keen, enthusiastic and valued employee. He describes him as a nice young man and nobody wanted him to experience something as awful as this."
The business, which has relocated since the accident to Blidworth, had no previous convictions.
After the hearing, HSE inspector Samantha Farrar said:
"This incident could so easily have resulted in a fatality and was entirely preventable.
"It had become the usual procedure, when pallets were leaning or unstable, for employees to walk alongside forklift trucks to hold the loads steady. It was this unsafe practice that led to serious injury.
"Vehicles at work are a major cause of fatal and severe injuries with more than 5,000 incidents involving workplace transport every year. Providing a safe system of work based upon the findings of a suitable risk assessment and adequately training, informing and instructing of staff makes incidents such as this significantly less likely."
