A worker at a brewery that makes Budweiser beer was sacked for raising safety concerns, a union has claimed.
Paul Morley, a senior health and safety representative at AB-InBev Brewery in Preston, was dismissed on 13 June, the GMB union said.
Mr Morley had claimed bosses had not conducted a proper assessment into fatigue due to a new process to speed up brewing, a union statement said.
AB-InBev said health and safety was their "number one priority".
The company, which owns Budweiser, said it could not comment on individual cases, but added: "We are confident that all processes adhere to our high standards of health and safety, as well as legal requirements.
"This has been confirmed using a certified assessment tool from the UK body, the Health & Safety Executive."
'Talks to continue'
The GMP said brewery staff would vote on whether to strike due to their concerns about Mr Morley's dismissal.
GMB regional organiser Shaun Buckley said: "Paul Morley has been sacked simply for trying to look after the wellbeing of his colleagues. It's a disgrace.
"The GMB understands management may want to streamline processes. All we ask is they follow the appropriate health and safety assessments in doing so."
An AB-InBev spokesman said the firm would continue to have discussions with union representatives.
