"This type of always-on mentality is something that many companies are learning to combat because it is unhealthy and a leading indicator of bigger issues down the road."
This is something I've struggled with on and off during my career. I like my work and want to help things move along where I can, but being always-on impacts on my family life long-term.
I like the "unfocused" part. Constant context switching and lack of understanding priorities is a silent killer. As a lead I try to protect my crew from working on too many different types of projects concurrently because it makes it impossible to really go deep which causes the output to suffer and is less fulfilling for the developer.
