I feel cubicles are better than open plans.
Allow people to WFH. Personally, I don't mind in office work, but I prefer mostly from home (I am raising the future work force).
Commutes are horrid. Here in Seattle, road rage shootings are common. In San Francisco, on the BART, one could get into an accidental fight with strange people.
Make sure the bathrooms are clean, and don't assume men's bathrooms should be smaller. I find it absurd to stand in line.
Free coffee and candy are not perks.
Homogeneous workplace application is a thing of the past. Flexibility is the future.
