Jockeys are to boycott a race meeting at Wolverhampton next week because of safety concerns over a new team of stall holders.
Having been approved by the Jockey Club at tests at the start of the week, the new team of stalls handlers assembled by Arena Leisure are due to start work at the meeting on Monday.
But at the Jockeys' Association Annual General Meeting for Flat jockeys in York, the jockeys unanimously agreed they would not accept booked rides for the fixture in support of the Racetech handlers who have lost work as a result of Arena's cost-cutting measure.
However, JAGB chief executive John Blake said the association would support any jockeys who do decide to take rides.
"The big issue arrived at by a number of our members is what this deal will do to the future of Racetech and the stalls handlers employed by them," he said.
"We are led to believe some of them are being asked to return on a casual basis from next spring, but what are they supposed to do in the meantime?
"What happens if Racetech decide to stop supplying stalls handlers as a result of losing this work? We could have microcosms of what has gone on with Arena happening in pockets up and down the country and the implications for the safety of horses and jockeys if that happened would be frightening."
Mr Blake stressed by turning down rides, jockeys were prepared to lose out financially.
"Jockeys don't want to hold racing to ransom but they do want to show their support and their strength of feelings about what they consider to be an important issue," he continued.
"And the feedback I have had suggests there is very much a sense of unanimity over this."
Having officially approved the new team to start work, Jockey Club officials admitted they could only "monitor the situation".
"As far as we are aware, the JAGB members don't have a specific concern as regards the safety of the new arrangements," said public relations manager Paul Struthers.
"We would only take action against a jockey who failed to take a ride for which he was booked."
Jon Pullin, racing operations manager to Arena, expressed his disappointment at the jockeys' move in light of the official approval given to the new team of handlers.
"I am obviously disappointed the jockeys have decided to take this route, especially after we received Jockey Club approval for the team to start work at Wolverhampton next Monday," said Pullin.
"We are disappointed the jockeys or a member of their association did not come to the tests to see the team is competent."
