Hundreds of Jacob's Bakery workers in Liverpool are facing redundancy as the company has announced big changes to its Aintree factory.
Jacob's owner Pladis said an upcoming "significant investment" at the factory will result in the overall size of the site being reduced, putting up to 361 jobs at risk from December 2024.
The site currently employs 763 workers from the local area.
Lisa Ryan, GMB union regional organiser, said: “This decision will leave many workers feeling frustrated and worried.
"In the run up to Christmas last year, GMB members at the site were on the picket line fighting for better pay. The workers won the pay they deserved. And their reward is redundancies. Jacob's have sunk to new lows. We will fight tooth and nail for the best outcome for Jacob's workers.
A Pladis spokesman said: “Jacob's is one of the most iconic brands in the UK and has been around for over 100 years. To ensure it can remain for another 100 years, it is essential we address the current constraints we have at Aintree. We have therefore proposed some changes at the site which include a significant investment in the infrastructure but reducing the overall site footprint.
"This proposal will now be subject to consultation with our employees as it could result in a reduction in roles at Aintree from December 2024. We will do everything we can to support our colleagues through this uncertain time.”
