More than 200 workers at a manufacturing plant in Surrey have been told the site could close.
SC Johnson manufactures home cleaning products at its base in Frimley including brands such as Mr Muscle cleaners and Glade air fresheners.
Chris Beard, public affairs director, said the firm had to be more flexible, faster and responsive to its customers.
He said the global business had other sites around the world which were better able to meet customers' needs.
Mr Beard said: "We did inform employees last night that we are making the difficult decision to go into consultation process over the future of manufacturing at Frimley.
"It is a family company. We care a lot. It is a hard decision."
He said if the decision at the end of consultation was that the plant would close, SC Johnson would go "above and beyond" to help workers with measures including six months' notice, job search support, and a generous severance package.
He said: "It's been very difficult but ultimately it came down to the need to be more flexible, faster, and responsive to our customers.
"We manufacture in many places around the world, and we have places around the world able to meet these customers needs."
In total, more than 200 workers are based at the plant.
Mr Beard said consultation would run for a couple of months. If closure was agreed, manufacturing would be phased out and the process would take six to 18 months.
He added: "We are a family company with our headquarters in Wisconsin. When it is a family-run company, we don't take this decision lightly."
