Disabled workers who lost their jobs when their factories closed, occupied the head office of the company where they used to work today.
The GMB said the action at the offices of Remploy in Leicester, was part of a fresh initiative to save jobs.
Unions have held a series of strikes at Remploy factories and have announced a four-day walk out at sites in Chesterfield and Springburn, Glasgow, from August 28.
GMB national officer Phil Davies said: "We are asking the public to support our members who are trying to find out who they will be working for as no information about the sale of these two factories has been given to the employees or the trade unions."
Half of Remploy's 54 factories are to close by the end of the year, 18 will close or be sold next year and the remaining nine face an uncertain future.
A number of factories closed last week under controversial Government plans to switch spending to help individual workers find jobs in mainstream sectors.
