Working from home? Like they have a choice.
Their idea of making people work in the office, and the subsequent closing down and centralization of offices, was a ploy to cut expensive headcount and offshore jobs. When the older workers quit or were fired when they couldn't move, the job were offshored or opened to newbies making much less. Many of the offices were ill equipped to handle the influx of people and the facilities weren't kept up to date in some cases.
The reality was that someone with roots moving a long distance for a job that may not last anyway isn't all that appealing. They knew this.
