We are living in a 24/7 global society in which many businesses, industries, and services around the world operate non-stop, which is great for production, customer satisfaction, and even safety.
We can hop on a jet at 1:00 a.m. to fly halfway around the world, we can visit a hospital at 1:30 a.m. to seek treatment for a bad case of the flu, we can head down to a convenient store at 2:00 a.m. to pick up a box of diapers, we can call tech support at 2:30 a.m. when our internet stops working, we can even hit the drive-thru at a fast food restaurant to get a late night snack at midnight.
The quality and convenience afforded us by having businesses operate 24 hours a day is staggering. It's hard to imagine there being any drawbacks.
However, there is a very real problem with having all of these services available at any time of day or night: somebody has to work during those hours.
