Transport workers are putting up with higher than ever levels of abuse and anti-social behaviour.
The problem is highlighted in a new survey of 600 transport staff published this morning.
SIPTU is launching a major new campaign for legislative and societal level change to curtail the high level of abuse and anti-social behaviour directed at public transport workers.
More than one-third of transport workers in Ireland believe abuse and anti-social behaviour is a serious issue.
SIPTU's Adrian Kane has said it's time for change.
"What's come back very clearly in relation to our survey is that first of all, and probably most startling, over 50% of people experience anti-social behaviour either on a daily or weekly basis," he said.
"The vast majority of workers believe that the situation has got worse in the last 12 months.
"Over a third of workers see it as a serious issue.
"I think we've transitioned from a situation where we're one the few countries where people say, 'Thanks' to the bus driver to a case where now more people are abusing transport workers.
"That has to stop," he added.
The launch will include the release of a series of campaign videos and a new 'Respect Transport Workers' badge.
