I remember a few years ago when a company merger took at our place of work, our division took the brunt of the fallout. A number of people lost their jobs, and it was left up to those 'lucky' few who were left (that meant four of us) to handle the messy transition of that department.
It was, well, overwhelming. There was little time for anything else, with work-related tasks and activities taking priority. I'm not saying that family requirements and social events were totally ignored, but they did get overlooked and attended to as and when, with frequent reminders being necessary for me to remember, from my wife and children. It was something that wasn't necessary before. Ever. Slipping into this workaholic mode was so insidious I didn't even realise how it was taking over my life, and the effect it was having on me and those close to me.
