When they saved money by reduced office space, did they pass on any of those savings to employees? Of course not. 'That is OUR money.' However, if you are based at home in an area far away from any city, they want to adjust your pay accordingly. Jaw-dropping hypocrisy.
They are the epitome of corporate greed and unrepentant unethical behavior.
They also have the temerity to leverage your sense of ethics and 'supporting the team', when they would let you go at the drop of a hat. Your evenings and weekends mean nothing to them.
