SalesForce is a company. Their job is to make money for their share holders.
That attitude has been destroying the U.S. economy since the 1970's. The priorities of any sane company should be:
1. Provide a good or service that delights customers
2. Make enough money doing it to pay your vendors and employees fairly
3. Reinvest most of the profits in ways that will provide long-term benefit (capital upgrades, employee training, etc.)
4. If you are publicly traded, pay shareholders just enough that they don't dump your stock
If SalesForce were focused on the first three, then unless they're already at 100% market saturation, they could find profitable new tasks for those workers.
They have chosen not to, because "shareholder value" is more important to them.
