First of all, let me state that this post is a personal opinion. And, like any opinion, it relates to an individual's personal feeling and it's subject to interpretation. You can disagree with it. Also, note that I'll be using Christmas and the first day after New Years Eve as examples and I think they are actually the only two exceptions to my opinion.
So, I think Holidays are efficiency killers. Don't get me wrong, I'm even more addicted to my personal life than I am to my work, but there's just something wrong with our current calendar. Let me explain: This year, both Christmas and the first day after New Years Eve are on Thursday. For the "typical job", what that means is that we work 3 days, stop one day, then work Friday and then there's the weekend. This is bad news. It's a rhythm breaker. What I mean is that I like holidays, just like everyone else, but in our current world, we should consider adapting the holidays to a more logical calendar. It would be like a "disk defragmentation tool":
If you're spending the weekend 400km away from your work and someone tries to schedule a meeting to that same location on a Thursday, what would you do? Probably postpone the meeting to Friday right? That's efficiency: take the best out of the available resources in order to achieve a given task. If your birthday is on a Wednesday, you'll probably postpone the celebration party to Friday or Saturday because that way people can take the most out of the night (assuming they don't work on weekends). Why not do the same with holidays? If a holiday is on Thursday, why not move it to Friday? Apart from religious beliefs and similar issues, I can see no disadvantages on this "defragmenting" process. As a professional, It would be great: no rhythm breakers (not only for me, but because everyone else's rhythm breaking affects my work). As a life lover, three days in a row would allow much more fun and travelling.
As I stated in the first paragraph, I think Christmas and the first day after New Years Eve are actually the exceptions to the "defrag rule". And I know that due to religious, political and even financial issues this would be hard to implement, but it would be great...
