Members of construction workers’ union Ucatt have voted to merge with Unite, forming one large union for the sector.
The formal transfer from Ucatt to Unite will take place on 1 January, but in the meantime the unions said the move put “bad bosses on notice”.
“Bad bosses and construction firms employing sharp practices should beware. Our new combined industrial voice will be used to defend the rights of construction workers across the UK and to campaign for secure decent jobs which pay the rate for the job,” said Unite general secretary Len McCluskey.
Ucatt acting general secretary Brian Rye added: “By joining with Unite, the industrial muscle of all construction workers will double overnight, which is good news for all members.
“Employers are going to have to get used to dealing with one voice and one union. They need to understand that shoddy and underhand practices including; dismissing workers without warning, exploiting workers by paying them via agencies or umbrella companies and ignoring key safety laws will not be tolerated and will be exposed.”
Both Ucatt and Unite, as well as trade union GMB, played a key role in the recent “blacklisting” case involving the Consulting Association.
