Remploy staff in Birkenhead and Aintree plan to strike this week in protest at government-backed plans from the company to close 28 of its 83 factories, which employ 5,000 disabled people.
A two-day walkout is planned for Wednesday and Thursday at the Merseyside factories, which are among those earmarked for closure by the publicly-funded company.
Unions GMB and Unite are also expecting results for a strike ballot at the York factory this week, with the outcomes of votes in Hartlepool, St Helens, Treforest and Ystradgynlais, near Swansea, and Brynammon, South Wales, due next week.
Remploy trade union convenor Les Woodward said this coming fortnight would be crucial for the unions' campaign to halt the closures.
