The death of a man who was buried alive when a trench collapsed on him was accidental, an inquest jury has ruled.
Callum Osborne, 24, was laying pipes at a building site in Whitstable, Kent, when he was killed in April 2011.
The father-to-be had been working as a labourer for just two days, the hearing at the Guildhall in Sandwich was told.
Mr Osborne's partner said she was disappointed by the verdict. The Crown Prosecution Service said there was not enough evidence to make a prosecution.
The inquest was told Mr Osborne had been asking for work from the building firm Cooper Services Ltd for a number of weeks before the company decided to give him a trial.
On his second day, he was working at the site in Bridgefield Road, laying pipes in a trench that was 1.6m (5ft) deep and about 33m (108ft) long.
The trench collapsed, killing Mr Osborne, who was weeks away from becoming a father for the first time.
His partner Colette Osborne said she was "extremely disappointed" with the verdict of accidental death.
"His death has destroyed many lives and has left a devastating impact on everybody," she said.
The Health and Safety Executive will now decide whether it has enough evidence to bring any further legal action.
