Eight mill workers who lost their jobs due to the imminent closure of a Harris Tweed mill on Lewis are taking their case to an industrial tribunal.
KM Group helped meet an order for tweed for a sport's shoe
They claim they were unfairly dismissed by the KM Group, which owns mills in Shawbost and Stornoway.
The Shawbost mill is to close as part of a restructuring of the business.
The Transport and General (T&G) union claims it received no official notification of the pay-off, as it was entitled to.
It said 20 staff had lost their jobs.
KM Group owner, Derick Murray, denied the claim and said 16 staff were paid off.
The tribunals office is expected to hear the case within the next few weeks.
In 2004, the group helped meet American sportswear and fashion giant Nike's demand for tweed for a women's trainer.
