Crown Care Home in Harwell closed by Four Seasons Health Care
Residents at an Oxfordshire care home have been told they will need to move as their current home is to close.
Crown Care Home in Harwell used to be run by Southern Cross until its collapse in October 2011.
Four Seasons Health Care then took over the converted public house but has now dubbed it "not fit for purpose as a modern care home".
The home will continue operating until alternative arrangements can be made for residents.
A company spokeswoman said it could not continue with seven residents being looked after by 20 staff, but is offering the staff work at other homes in the area.
Justin Bowden, National Officer for care homes at the GMB union said: "Residents and staff at Four Seasons have good grounds to worry that this closure in Oxfordshire is the thin edge of the wedge.
"GMB members at Four Seasons are entitled to ask if it is linked to the £780m debt mountain due to be repaid in September."
But a spokeswoman for the company said: "It is mischievous nonsense to suggest the closure is for any other reason than the one we have given.
"We believe this has more to do with the campaign the union has been running against Four Seasons since we declined voluntarily to give them recognition for bargaining rights."
