I've just remembered... true story which explains a lot of the stories here.
I'll not name names to proyect the innocent....
Scene: a Sony plant somewhere in the UK. Sales are in decline as technology changes. Managers don't read the signs, or see what's coming. They ended up cutting a shift.
They did some good things: lots of advance notice, a jobclub set up in canteen, unions fully informed.
On their last night, the outgoing shift wrecked the joint. Floor sweepings in the plastic moulding hoppers, etc. £1000s of damage and lost production.
So what happened when further redundancies became necessary? There was no warning.. Extra security led them to the entrance foyer, where they got their cards.
Mind you, the company did fail in one way. The management had been recruited mainly from the food industry, which had done well in the previous recession.. People have to eat... Trouble is, they had no feeling for the core businesses of Sony. They did not see new media and products coming, and didn't listen to those who read the runes right. The Sony plants in Holland, managed mainly by engineers, did see it coming, and positioned themselves to shift to new products.
It's not the Sony problem- it's the British problem. Look at the collapse of great TV companies like Granada, and British Airways, and think of the Irish boom which led to the hiring of Irish foodie managers.
