The long-term perspective.
I hope you're getting paid for all those evening hours ... They add up quick!
Many moons ago we were given pagers to carry "for emergencies". I turned mine on when I got to work, and off again when I left work. My reasoning was that I wasn't being paid when I was off work, therefor they had no right to try to contact me. Needless to say, management wasn't very happy with my interpretation. They called HR, to get me to see reason or to fire me. HR took my side (!!!). Long and short of it, everybody with a pager wound up with an extra dollar per hour for each and every hour we were required to be on call when otherwise off duty.
A couple years later a few of us were presented with DynaTacs ... we all said "more money, please". This time, we were compensated $1.75/hr. For awhile there I was collecting for both the pager and the phone. It was quite lucrative, added up to a hair over $18,000/yr in mid '80s dollars. Fortunately Upper Management liked me more than they liked the mid-level idiot who ran our division ...
Then Middle Management discovered email. Every single last one of us refused to use email out of hours because actually sitting down and typing was entirely too disruptive to our RealLife. That was the end of it ... until the Blackberry made email a telephone thing (yes, I know, there were attempts before the Crackberry, but RIM put the concept on the map, at least for the non-technically inclined). Thankfully, I was already out of the 9-5 loop by the time that happened.
Daftest thing is that you idiots actually use YOUR OWN EQUIPMENT to do your company's business! WTF are you thinking? If they need you to check your email outside of working hours, Shirley they can bloody well pay for the gear required to do so, right? The entire BYOD thing boggles my mind ... how much money are corporations, world-wide, saving by forcing workers to pay for the privilege of doing their jobs?
And then there is the actual meaning of "BYOD", to wit "Break Your Own Defenses". One wonders how many emails world-wide are being opened at home as I type that would get the user fired if he printed it out and tried to carry it out of his office at knocking-off time ...
Suggestion: It's called a 9-5 for a reason. Treat it as such. Leave work at work, even if "work" is a company-issued laptop on your kitchen table. Close it after hours, and LEAVE IT CLOSED until after breakfast tomorrow. Your life will be a lot happier.
