Excerpt from this article:
Can social media thus shine a spotlight on workers’ stress levels? The authors of a new study analyzed a database of more than 2 billion tweets from almost 47 million individuals during an 18-month period. After filtering for only English-language tweets with the words “work” or “job” in the post, the authors were left with a sample of more than 8 million work-related tweets, or about 3.65 percent of all the tweets that were sent in the U.S. during that time.
…To examine weekly trends, the authors aggregated the text analysis results to correlate with the days of the week — all the Mondays together, all the Tuesdays together, and so forth. They could then calculate which days, on average, featured the most tweets about work-related stress.
Everybody really does hate Monday, it turns out. Tweets with mentions of work stress peaked at the beginning of the workweek and slowly declined through Thursday. On Friday, there was a much steeper drop-off, suggesting that people either are mentally ready to be out of the office or don’t see much point in discussing stressful work circumstances with the weekend rapidly approaching.
One would think the pattern would continue and that workers would largely feel stress-free when away from the office Saturday and Sunday. However, the analysis uncovered a different pattern: Negative emotions and stress-related comments don’t decrease steadily from Friday through the weekend, but actually begin to pick up Saturday and increase markedly on Sunday. Clearly, the “Sunday blues” are no myth — people begin fretting about their jobs as the weekend draws to a close and the stresses of Monday morning loom on the horizon.
