The High Court has granted an injunction preventing workers blocking trucks entering and leaving the premises of a waste disposal company that collects more than 110,000 households in Dublin.

The court heard that the workers placed a blockade outside Greyhound Household Ltd depot in Clondalkin as part of a dispute over pay at the company.

The injunction does not prevent the picket continuing.

Mr Justice Max Barrett granted the company a temporary injunction preventing 60 named employees, the trade union SIPTU and anyone who has notice of the orders from interfering with access to and from the plant.

The order was granted on an ex-parte basis, meaning only one side was represented in court.

The matter was adjourned to Thursday.

Seeking the injunctions, lawyers for the company said the blockade commenced early this morning.

No bin collections involving lorries from the deport had taken place since the blockade started.

It was also claimed that drivers in bin lorries were subject to intimidation by workers involved in the protest.

The company said that while there had been a meeting by its members about the company's restructuring plans last weekend,

it had no prior notice of any industrial action.

It accepted there is a trade dispute between it and its employees over pay.

However matters escalated this morning.

There was a major concern about health and safety, and already one person involved in the blockade had been injured after being struck by a truck, the court heard.

The company said it also had concerns that what was happened had been mischaracterised on social media.

Already the dispute had been called a lockout of workers on Facebook. 

The company said this was not the case, and that any employee who wished to return to work was perfectly entitled to do so. 

Workers earlier claimed they had been "locked out" of work because they refused to use a new clocking-in system.

The workers arrived at the plant this morning and said they were asked to clock-in. They claim they had no notice of the new system.

Management said it was part of the terms and conditions negotiated as part of a Labour Court agreement.

Greyhound said disputed cuts were agreed two weeks ago by the Labour Court.

Workers say the proposed pay cuts could see driver wages being cut by up to €300 a week.

They say the cuts are unfair and unjust.

Management said it is going ahead with the implementation of the Labour Court agreement.
