One of the biggest employers in the Forest of Dean in Gloucestershire, may be shedding more jobs.
The Transport and General Workers Union says it has been told that Watts Tyres of Lydney is considering closing one of its divisions.
The production line for industrial tyres could be moved abroad with the loss of 30 jobs.
A little under a year ago the company -which employs about 300 people - moved 35 jobs overseas.
A statement from the company is expected later on Thursday.
