It's not the moment for asking for a salary increase.
Well, we are not Greece.
Austria's economy is growing by 4% this year, so are the profits of the companies. The inflation is also at about 3.5%.
Therefore it is only normal that the steel workers (and others) get at least a 4.5% pay rise.
The employers representatives demand that wages should only rise by 3% this year is ridiculous because it would mean a net wage loss because of the inflation.
It's good that the unions are turning up the heat on the capitalists. It's good for the middle-class.
If salaries should be increased according to GDP (a thing that the forces of the market would correct without any policies a year later), when you have a recession you decrease salaries? That's nonsense.
Also, you are not Greece, but you are an eurozone country. Things could change quite quickly.
