Mostly people prefer to working at home just due to flexibility of time.
I wonder if there was a choice of work from home for 80% or from the office for 100% of salary, would people choose flexibility?
In general, a payrise only impacts positively for two months. The first month is the feeling of getting the payrise, the second is spending it on something. Then, it is gone, soaked up into lifestyle.
It depends on their financial crises that which will they choose!!!
