Penzance RMT union strike over dismissal
A 24-hour strike by First Great Western (FGW) staff has started over the dismissal of a manager.
Members of the RMT union in Penzance walked out at about 04:00 GMT and are also set to take 48 hours of industrial action from 06:00 GMT on Easter Sunday.
FGW said the man was sacked for breaching safety guidelines but RMT urged the train company to "see sense and reinstate" him.
FGW said there had been no impact on services.
A spokesman said: "We can confirm that a member of staff was recently dismissed for allowing the doors of a train to remain open while in passenger service, and failing to report the incident to anyone for over a month.
"The member of staff was not an RMT member at the time of the incident, and we are surprised that they have decided to support these actions, which put his safety, and the safety of his colleagues and our passengers at risk."
RMT General Secretary Mick Cash said: "It is clear that there is a culture of bullying and intimidation of staff in the money-spinning operation which is First Great Western.
"We will not allow this culture to go unchallenged."
