Employees are spending time on the clock dealing with their personal finances, and it negatively affects their productivity. According to a Harris Poll conducted on behalf of Purchasing Power in March of this year, 37 percent of U.S. employees working full-time report that they spend time at work thinking about or dealing with their finances.

On average, they're spending two hours every week balancing their budgets, worrying about paying down debt and dealing with other money concerns. Large businesses are potentially losing millions of dollars in lost productivity every year.

Money tops employee stressors

Employees bring their financial stress to work because it's their biggest stressor. According to the American Psychological Association, Americans have cited money as their top source of stress since 2007. In order to find out what kinds of financial issues keep them up at night, we surveyed working Americans on their financial situation:

• 34 percent have trouble meeting monthly expenses;

• 40 percent don't have at least $2,000 saved for emergencies; and

• 26 percent of employees who consistently carry balances on their credit cards find it difficult to make minimum payments on time.

American workers are stressed because many are in a precarious financial situation. It's difficult to focus on your work when you're worried about making a large purchase or paying your monthly bills.
