If you look at news sources outside your right wing echo chamber, here is an alternative perspective of exactly the same news story when it isn't been brainlessly cheerleaded as some sort of victory:
"Nissan’s Sunderland manufacruring is to stay open, but the carmaker is instead shutting a factory in Barcelona as the Japanese auto firm seeks to cut £2.3bn in costs worldwide.
The decision will mean the loss of 2,800 jobs in Spain but removed a short-term threat to most of the 6,700 jobs at Nissan Sunderland Britain’s biggest car plant.
However, the carmaker said it would seek to “improve efficiency” at the factory in the north-east of England as it revealed a plan to reduce annual spending by ¥300bn (£2.3bn) worldwide."
So long term future far from guaranteed, nor are all those jobs. "improving efficiency" by companies running at a loss tends not to involve hiring more staff.
