New research has found American workers took an average of 17.2 days of vacation in 2017, up almost a half-day from 2016.Project: Time Off, who are affiliated with the U.S. Travel Association, says "this marks the highest level for American vacation usage since 2010 (17.5 days) and more than a full-day increase since bottoming out at 16 days in 2014."But maybe these aren't enough days as 52 percent of Americans left an "accumulated 705 million unused days" in 2017, which has increased from 662 million in 2016.How? The increase in unused days, despite Americans taking more vacation, is attributed to employees earning more time off (23.2 days in 2017, compared to 22.6 in 2016).Further, nearly 25 percent of Americans have not taken a vacation in more than a year.Some possible barriers?  807

NEW YORK (AP) — Americans held back on spending during the start of the holiday shopping season, a troubling sign for retailers and the state of the U.S. economy. U.S. retail sales fell a seasonally adjusted 1.1% in November, according to the U.S. Commerce Department. It was the biggest drop in seven months, and a steeper decline than Wall Street analysts had expected. The Commerce Department on Wednesday also revised October’s report, saying that retail sales fell 0.1% that month, instead of rising 0.3% as it previously reported. Retailers had tried to get people to shop early, with Amazon, Best Buy, Walmart and others offering holiday deals in October.The report points to a weak start to the all-important holiday shopping season, which can usually account for a quarter or more of a retailer’s annual sales. Black Friday was also a bust. Typically one of the busiest shopping days of the season, shoppers mostly stayed home after health officials warned people not to shop in person, and retailers followed suit by putting their best deals online. Half as many people shopped inside stores this Black Friday than last year, according to retail data company Sensormatic Solutions.“It will take a miracle to keep retail sales positive in December,” said Chris Rupkey, chief financial economist at global financial group MUFG.It is also another sign that the pandemic is slowing the U.S. economy as stores face tighter restrictions and people stay away home. 1475

New research confirms that temperature and symptom checks miss many coronavirus infections. A study published Wednesday found that these measures failed to detect infections in new Marine recruits before they started training, even after several weeks of quarantine. Many recruits had no symptoms yet still spread the virus. Genetic testing revealed six separate clusters of cases among the recruits.The work has implications for colleges, prisons, meatpacking plants and and other places that rely on symptom screening. Doctors say more COVID-19 testing is needed, especially in younger people who often don't develop symptoms.An estimated 20% of coronavirus infections do not result in symptoms. The good news is those who are asymptomatic generally do not spread the virus as easily as those who have symptoms, according to a University of Minnesota study. 868

NEW YORK (AP) — “Sesame Street” has always pressed for inclusion. Now in the wake of the national reckoning on race, it’s going further — teaching children to stand up against racism. Sesame Workshop — the nonprofit, educational organization behind “Sesame Street” — will air the half-hour anti-racist special “The Power of We” and hopes families will watch together. The special defines racism and shows how it can be hurtful. It urges children who encounter racism or hear someone else be the victim of it to call it out. The show will be composed of skits and songs in a Zoom-like format that will stream on HBO Max and the PBS 24/7 streaming channel Oct. 15, and air on PBS Kids the same day.Gabrielle the Muppet advises: “When you see something that’s wrong, speak up and say, ‘That’s wrong’ and tell an adult,” 824
