Doesn’t bother me and yes, I believe it improves productivity.
Can you imagine what would happen to productivity if people started showing up and leaving based on whether the sun was out or setting?
Additionally, employers might say “Fine, you got all them hours off during winter. Now, you can make it up all summer long”.
“This ain’t no clock factory! Now quite making time and get to work!”.
Well, you are literally the only one I’ve ever met who has said the time change doesn’t bother them. You don’t happen to have a sleeping disorder, do you? I know it doesn’t affect everyone the same way, but most people are affected by it to one degree or another. For both my wife and I, the effect it has happens to not much different than going to work drunk. There’s no possible way it’s gonna make me (and a lot of other people) more productive.
Regardless, getting up based on the time on a clock (as opposed to whatever the sun is doing), is not at all the same as changing the time on the clock every six months. Most people are still going to be working the same number of hours per day regardless of whether there is daylight saving time or not.
