Workers based at BiFab’s Methil yard are calling for talks with their bosses to address a number of outstanding issues.
It comes after the entire staff walked out last week in support of 24 men employed at the plant by sub-contractor Kaefer C & D.
The men, who were striking because of a dispute over their rate of pay at the company, which also has premises in Burntisland and on the Isle of Lewis, returned to work last Wednesday after successful talks with Kaefer bosses in Burntisland on the Tuesday.
However, several of the remaining BiFab workers took the decision to continue the strike until the end of the day on Wednesday because, they say, of a lack of opportunity to gain direct employment with the company.
Rab Sherry, regional officer for Unite union, said: “Only one in 10 men who work at BiFab are directly employed by the company.
‘‘The rest are employed through agencies.
‘‘They have no job security - they could be here today and gone tomorrow.
“Whenever the issue is brought up with BiFab, it always maintains that when a new contract is picked up, it will employ more direct employees, but that promise is broken each and every time.
“Some of the men working at BiFab have been employed there through agencies for years. It’s unacceptable.”
Mr Sherry said Unite and GMB have called on BiFab bosses to set up talks with workforce and union representatives to clear the issues, but have had no response so far.
BiFab declined to comment.
