A Week's Worth

• China's move to disconnect its currency from the dollar could turn out to be a historic shift. If, as expected, the value of the Chinese yuan goes up against the dollar, Americans would begin paying more for imports while American factories would find it easier to export their goods. That could help narrow the trade gap, although the first revaluation turned out to be tiny. The dollar, which fell sharply after China's announcement, recovered some of its losses on Friday.

• Help wanted: Companies in June posted 1.4 online job ads per 100 people in the labor force, but results varied by region. New England scored the most (just over 2) while Arkansas, Louisiana, Oklahoma, and Texas offered the fewest (just under 1 online job ad per 100 people), says the Conference Board. In a separate report, Challenger, Gray & Christmas reported that job seekers were finding work more quickly - 3.1 months on average in the second quarter compared with 3.8 months a year ago.

• Playing hooky: Nearly a third of workers say they've taken a sick day even though they were perfectly well. Their main reason? They needed a break, says a survey by professional staffing firm Hudson.

• Lunch is losing its appeal as nearly 6 in 10 workers say they skip their midday meal when they get too busy. Four in 10 say they eat in 15 minutes or less, according to a survey by Smoothie King Franchises.
