I think they have already done that. I think they have alreadys sold over £100m of land and buildings off.
Unfortunatly this is RM saying up yours. The are purposely running at a lose so they dont have to give decent payrises.
The selling off of real estate is pretty normal in companies these days though. My employer had a number of big offices and factories, that they've sold off and just rent office space now. They've owned these buildings for decades but obviously land has massively shot up in value, and I guess with offices not needing much space anymore it was a bit wasteful keeping them all.
