Protesting workers at the Vita Cortex plant in Cork have told management that the gates to the premises will remain locked.
The former workers blocked the factory gates last Friday.
This was to stop lorries operating to and from from a sister business, Vita Clean, on the same site.
There are between six to eight people employed at Vita Clean.
Protesters made their intentions clear to a company representative who visited the plant this morning.
Meanwhile, SIPTU have made no official comment on the workers' action.
A spokesman for owner Tipperary man Jack Ronan said this morning he was considering this latest development and a statement may follow this afternoon.
The sit-in at the Kinsale Road plant began 109 days ago.
