About a month ago, I put in leave for the first time in 4 years. I rarely take the day off, so this was a big deal. And, I felt kinda guilty doing it. Even though the rest of the team took their time off, I felt I had to be the responsible one.
Well, the week before the leave was to occur, we had an "important demo" to get ready for. This demo was something out of the blue, but I was asked to still work during my leave. I said "OK" an was really pissed.
That night I couldn't sleep. I felt that I put in all my quality work, why can I not take my proper leave like everyone else? The next day, I put my leave back in and took a nice restful week off last week!
The world didn't end. I'm still employed, and the demo (the all important demo) was canceled because other devs haven't even finished their work.
It felt good to be detached emotionally. Never again will I sacrifice my personal time again at work. Its not worth it to yourself, and also to the company.
