''Starters, barrier attendants, the clerk of the course, swabbing and other raceday staff are involved,'' the website's story said.
However RV countered on Saturday afternoon in a bid to allay any public concern over disruption.
RV says that only some 20 per cent of the racecourse staff are unionised and that it has a contingency plan to cover for their absence should there be any walkout or stopwork action.
“It’s disappointing that the AWU have chosen to take advantage of the Spring Racing Carnival to threaten industrial action. We have been in good-faith discussions with the AWU and representatives as late as Thursday of this week. Despite this, we are committed to ensuring that all of our raceday officials benefit from a new enterprise agreement and will continue to work to that end,'' RV said in a statement.
“Given the AWU represent a small percentage of our raceday officials, we have a contingency plan in place to ensure that all feature meetings can proceed as scheduled so that owners, trainers, jockeys and racing fans are not impacted by their proposed action.
