Independent TD Joan Collins is encouraging industrial unrest within the public transport sector.
Joan Collins said Siptu should be rallying their members in Irish Rail and Dublin Bus for strike action in response to the Luas debacle.
Luas drivers will push ahead with industrial action tomorrow, in a series of rolling strikes over pay hikes.
Deputy Collins said: “Siptu should be going to those workers in Irish Rail and Dublin Bus and having a ballot for industrial action saying: ‘We have to come out behind the Luas workers.’
“If the (Luas) workers don’t get what they want in their pay claim, that’s going to impact the workers in Irish Rail as well.”
