Company ruthlessness and redundancy.

I left school in 1984 with no qualifications.
I started work straight away in a warehouse, and apart from redundancy due to factory closure worked continuously until 2009 when I was made redundant (for no specific reason other than my role was no longer part of the grand strategy).
I worked voluntarily until September 2010 when I landed a contract role with a large company.
I was then made permanent and now face redundancy again.
Four of us in a room, told one will go. Then the same four told only three will now go. We are being used as pawns to suit whatever plan the company is working towards.
I ask is this fair?
British companies are crying out for workers and yet when they get them they manipulate, bully and threaten them with the idea of teasing out the `best` while leaving the rest as redundancy wreckage. No longer is turning up for work and doing your job good enough. It’s all about continuous assessment, team play and having a face that fits with the ultimate aim of ridding themselves periodically of the so called `chaff`.
So, my question to you all is have you been down this road and is it fair?
I feel I’ve done wrong yet I excel at my job, have no time sick, never late and always do what i’m asked. Yet I feel I’ve done wrong, that I’ve failed? Ultimately I’ll loose my job?
Or is this just the sign of the times?

BTW I obtained my Degree and Certs in 2009, for what end I don’t know.
