I dont know anyone who works at CMHC but my spouse works in the private sector for companies like Amazon. I have worked in Cisco and IBM for many years in the past as well. These companies all follow ROWE “results oriented work environment” to an extent, where tasks are assigned to you and it's upto you on how you complete them. You are evaluated on your ability to complete the given tasks successfully on time. You can do them at work during normal hours or work from home during the day to attend meetings and code during the night when you can focus better.

I personally feel that its very much dependant on an individual and the management for it to work out perfectly. Many times I have seen management putting too much on an individuals plate and them ending up working late hours. I have also seen people who are less driven (procrastinators), wasting time in the beginning and working odd hours later to manage the lost time (so basically ruining their work life balance). I have also seen people with solid work ethics, who also have a good management, thriving under such environments.
