My Gen X generation would be used to office work but comfortable with modern technology. Although many times for complex subjects when you get into back and force messages "just call me" would enter my brain.
Millennial would be similar but grew up with more tech. Voice calls on phones would have been replaced by texts when they were young. Last golden age of TV was over so not much of a draw. I'd guess messaging would be more comfort that for all except the oldest audio voice calls. They be more comfortable working remotely but have certainly experience office life.
I'd Gen Z was born into tech never knowing TV and wouldn't care. Face to face in an office wold be alien for some maybe they never even had a job yet. Email would be ancient tech, messaging is basically speech and cryptic at that.
Basically I think there is a clash of culture and it depends on your generation how comfortable you are which results in how efficient of a worker you are.
