Striking Caterpillar workers have said they are being "stonewalled" in negotiations with the company.
Workers at the Larne and Springvale factories have been involved in industrial action over the past five weeks and are preparing for four more as they say that the company is "refusing to come to the table".
Speaking to Belfast Live, a striking worker said they feel let down by Caterpillar who are "offering a real terms pay cut" and saying they must take mandatory overtime in their contracts.
