I used to work at IBM in the UK in the mid 2000s and this was fairly accurate at the UK offices too.
We'd joke that IBM stood for I'm By Myself as people would work from home 90% of the time - many would be mysteriously uncontactable/AFK during that time due to "unforseen circumstances" (theat seemed to happen all the time) ... it was very hard to get hold of people when they were WFH.
No regrets - it was a great start for me, but I am glad I left.
