Landor Cartons pleaded guilty to breaching s 3(1) of the Health and Safety at Work Act and regs 4(1) and 6(3) of the Work at Height Regulations. It has been fined £200,000 and ordered to pay costs of £12,570.
Birmingham Magistrates' Court was told that, on 27 October 2017, the contract worker sustained fatal head injuries when he fell 6 m through the broken skylight on to the factory floor.
The Health and Safety Executive (HSE) found the company had failed to risk-asses working at height activities and implement a safe system of work.
HSE inspector Christopher Maher said: "Falls at height remain one of the most common causes of work-related fatalities in this country and the risks associated with working at height are well known."
