If they expect things to be bad, they have to cut cost. Companies are answerable to their shareholders. They cannot afford for things to turn bad before taking any actions.
So are they really deadwood or is DBS anticipating prolonged period of non-profitability?
If it's the first, they should not have been in the company in the first place. And having so many deadwood to get rid of speaks volume of the kind of company it is.
If it's the second, I still think they are using the axe way too soon. DBS has literally been profitably from day one. Sometimes, it has been obscenely profitable.
Easy for them to cut the 900 workers- whether they are deadwood or not is not the point.
