In my dynamic (with young kids), any attempts to work later than 20 min past the predetermined closing time are often met with baby/kids being "let loose" on Dad.
For the family, it's a plus. But sometimes ... holy shit I have stuff I need to finish.
Finally, it is SO convenient for spouses when their partner works from home. SO convenient. E.g. child care/babysitters fall through guess who gets to not get work done.
Overall, the ROI is pretty positive ... but I've been doing this a long time, and I do miss the office.
