There are always exceptions, including people who can't manage their time and those that don't have an adequate setup to work from home. We have an option to work from home several days a week but some people want to go into the office because it is a break from home or they don't have a dedicated workspace and typing at the dining room table doesn't work for them.

The big thing is that for those that can WFH successfully it is a huge positive for both happiness and productivity, and not having it as an option is a negative for them.
