Strike action by maintenance workers, quality technicians and fitters will bring production of aerated concrete blocks to a halt, their trades union said.
The Unite union members have voted overwhelmingly to reject a 4% pay offer. At other Tarmac sites, workers also get large bonuses for meeting targets, which those at Alfreton Blocks Plant are not eligible for.
Unite general secretary Sharon Graham said: "Tarmac is an extremely rich employer who can afford to pay our hardworking members the wages they deserve. It is completely unacceptable that these workers are paid less than colleagues at other sites and have been left struggling with the cost of living crisis while their employer makes such large profits. Tarmac must come back with a fair pay offer and the affected members will have Unite's full support throughout this dispute."
Unite members will walk out on 15th and 16th September and 22nd and 23rd September, shutting down production after 93% voted to strike.
As well as an improved pay offer, members at the Alfreton Blocks Plant have asked for an increase in the shift allowance and double time for bank holiday working. Although Tarmac has agreed to the latter, they have so far failed to negotiate with Unite on the other points, the union says.
Staff have also complained about the working culture at Alfreton Blocks Plant, with workers saying management don鈥檛 deal with issues that are raised while the factory has a retention problem leading to low staffing levels.
Unite regional officer Paula Stephens said: 鈥淎ll our members want is to be paid fairly for the job that they do but so far Tarmac has been avoiding discussions with the union. It is little wonder our members feel so disappointed in their employer鈥檚 actions.
鈥淭his will be a very disruptive strike which will completely shutdown the production line聽 but Tarmac still has the chance to come back with an improved offer that is acceptable to our members.鈥�
A Tarmac spokesperson said: 鈥淭armac has made an above-inflation pay offer which has already been accepted at other sites. Of the 65 employees at Alfreton, 20 have voted in favour of industrial action. Numerous meetings have taken place with union representatives, and concerns raised by employees have been addressed or acted upon.
"Production will not be shut down as robust contingency plans are in place so there will be no disruption for customers.
鈥淭armac remains committed to constructive communication and to providing a safe, supportive and rewarding workplace for all our colleagues.鈥�
