The union representing 350 workers who are facing the axe at Nottingham's Kodak factory says it will fight to keep the site open.
The union says the factory has a world-class work force
On Tuesday bosses announced a total of 600 job losses at plants in Annesley and Harrow in north London.
The Transport and General Workers' Union (TGWU) says managers could have done more to prepare for the consumer shift to the digital market.
The union says the 12-month notice gives them time to form a rescue plan.
Jim Mowatt, the national secretary of the TGWU, insisted the loss of the factory was not a foregone conclusion.
He said: "The members are very angry and shocked - after the surprise came the anger.
"We have a number of options; occupying the plant, industrial action, negotiation, going to the government to see if there is regional development funding available.
"If it comes to pass that the factory is going to close we will not sit back, we will see if we can find a purchaser for the site, which is a world-class site, highly maintained with a highly skilled work force."
Kodak currently employs about 3,000 people in the UK.
The company announced in January that it planned to shed up to 15,000 jobs worldwide over the next three years as it sought to reposition its business in the digital age.
