> According to Bureau of Labor Statistics, the average American works 8.8 hours every day. Yet a study of nearly 2,000 full-time office workers revealed that most people aren't working for most of the time they're at work.
The plain reading is that this article is based on BLS data. The BLS makes huge amounts of data available (and is friendly about answering questions), and the 8.8 hour figure is really theirs: https://www.bls.gov/tus/charts/chart1.pdf
But the second sentence is about unrelated research not conducted by the BLS, even if you trust that it exists.
This data looks bizarre. 23 minutes of smoke breaks? Only 15% of Americans smoke (https://www.cdc.gov/tobacco/data_statistics/fact_sheets/adul...), so if 85% of people spend 0 minutes a day smoking the other 15% spent 153 minutes per work day smoking. That can't be right, so this list must be the average time spent on an activity of all the people who reported engaging in it, which makes it pretty useless for understanding the overall situation it purports to talk about.
Assuming a study was done, this is probably self-reported data of a self-selected population. Ask 2,000 websurfers to break down their yesterday or last week of work and you're not going to get reliable data.
Without an accounting of methodology (or at least a citation), this article is an infohazard. People might read it an accidentally take it seriously, or remember these numbers but not remember they were completely unsupported.
