Another fairly common push back is the productivity argument - making sure the worker bees are in the hive when they're supposed to be AND actually making honey. It's also nothing that can't be addressed by management doing their job. I've been out of it for at least 10 years and when I left the technology to record everything happening in your cubicle existed and I installed some of it and took note of how little of it actually got used. I've busted more slackers getting over while being bored enough to play with the systems for a couple hours when baby sitting new installs than the entire supervisor staff did all day.
The dirty little secret? Your average-to-excellent performers tend to work more when they work from home, not less. Employers will never acknowledge that, but it's true. The slackers will do less, which is to be expected. That's why effective leaders root out slackers and performance manage them. They either improve and stay, or they don't and go.
