Workers across the broader building and construction sectors have overwhelmingly backed potential strike action if employers move to reduce their terms and conditions.
Trade union Connect said on Monday night that industrial action in the construction sector could also be triggered if a planned 2.7 per cent pay rise due at the start of October was not paid.
Separately it has emerged that the Government is set to to amend existing financial emergency legislation which would facilitate pay increases for public health doctors.
It has been established health service policy that public health specialists should be afforded consultant status following the publication of the Crowe Horwath report on the specialty in December 2018.
The trade union which represents public health doctors, the Irish Medical Organisation, said last week that public health doctors were playing a crucial role in the battle against Covid-19 but were just getting "lip service" for their efforts.
The Connect trade union, which has more than 20,000 members across the construction, electrical contracting and mechanical contracting sectors said there had been a massive vote of support for industrial action - up to and including strikes - in the event of employers seeking to reduce terms and conditions.
The ballot was held after the High Court found legally -binding sectoral employment orders negotiated between employers and unions on pay and conditions were unconstitutional.
The constitutional challenge to the sectoral employment orders was taken by electrical contractors. On foot of their case a proposed sectoral employment order for the electrical contracting sector was deemed void.
Appeal by the Government
However, the High Court subsequently deferred an order of unconstitutionality for two other sectoral employment orders covering the mechanical sector (including plumbers, fitters and welders) and the construction sector pending an appeal by the Government.
Connect said on Monday that members in the electrical contracting sector backed industrial action by 94 per cent, in the mechanical contracting sector by 96.7 per cent and in the construction sector by 97.5 per cent.
A number of other unions have organised similar protective ballots. However Connect is the only union that represents workers in all of the sectors affected.
Meanwhile the Government is set to amend financial emergency legislation which will facilitate pay increases for public health doctors.
Informed sources said on Monday that the Department of Public Expenditure and Reform would draft amendments to the existing financial legislation which currently prohibits pay increases for serving public servants.
It is understood that a memorandum will be prepared for the Cabinet before the end of September.
The Irish Medical Organisation (IMO) has been campaigning for some time for public health to become a consultant-led service and for public health specialists be awarded consultant contracts “to reflect their expertise and specialist skills”.
Public health specialists earn € 113,822 at present. Hospital consultants with a type-A contract - which permits them to treat only public patients - have a pay scale that ranges from €141,026 to €195,653.
The Department of Health last week told The Irish Times that it, the Minister for Health Stephen Donnelly and the HSE were "committed to the early introduction of a new model for public healthcare, as provided for the Programme for Government, and to the model incorporating consultant status for public health specialists".
