Keeping employees up to speed may be the best way to boost their moods during hard times, according to a survey by Accountemps.

In a poll of 150 senior executives from the nation's 1,000 largest companies, nearly half said better company-wide communication is the best remedy for low morale, the California-based staffing firm said. Despite the tough economy, just 13 percent of respondents said monetary awards were the best fix.

At the same time, 33 percent of respondents said a lack of open, honest communication in the workplace had the most negative effect on workers' attitudes. Micromanaging, excessive work, and failure to recognize achievements were also cited as practices that can damage employee morale.

The study said companies can create more positive and productive working environments by ensuring managers are available, willing to listen, and dedicated to getting workers involved.

"When people are concerned about job security and company performance, updates on corporate news are essential," Max Messmer, the firm's chairman, said in a statement. "By keeping employees informed, managers can address anxiety and ensure workers are focused on meeting objectives," he said.
