If you're feeling a sense of accomplishment at work, it's not your imagination -- it's probably just Tuesday. According to a recent survey, more than half (51 percent) of executives nationwide report the highest levels of employee productivity on Tuesdays.

Developed by Accountemps, a temporary staffing service for accounting, finance and bookkeeping professionals, the survey was conducted by an independent research firm that polled 150 executives from the nation's 1,000 largest companies.

The results of the survey closely mirror those of a similar survey conducted in 1987. However, while Fridays were still seen as the least productive work day, Monday's rating leaped from the fourth spot to become the second most unproductive day of the week.

"Monday may seem like the busiest day of the week for employees swinging back into the routine after a weekend off, but Tuesday appears to be when everyone puts their nose to the grindstone and accomplishes more work," observes Rob Hibray, a regional manager with Accountemps.

"The workweek appears to have its own business cycles during which productivity exhibits peaks and valleys," adds Lynn Taylor, vice president and director of research at Accountemps. "In today's corporate climate, however, companies may long for a week of Tuesdays in order to keep major initiatives on track."
