A new CareerBuilder survey reveals that 23 percent of workers rate their organization's current employee morale as low. Additionally, 40 percent of workers report that they have had difficulty staying motivated at work in the last year and 24 percent do not feel loyal to their current employer.

Workers revealed a variety of factors that could be contributing to low morale levels. Two-in-five said that their stress level at work is high and nearly half said that their workload has increased in the last six months. One-in-five are dissatisfied with their work/life balance.

Nearly two-in-five workers said they felt there was departmental favoritism at work, which could also play a part in low morale levels. More than a quarter of workers don't think their department is important to senior leadership.

Sales, human resources and accounting/finance topped the list of departments workers believe are primarily given preferential treatment at work.

When asked what type of preferential treatment workers thought the favored department received, they said that they:

• Tend to have higher salaries - 51 percent
• Receive more recognition by senior leaders - 47 percent
• Have more flexibility in their work arrangements - 43 percent
• Receive more funding/resources - 27 percent
• Tend to have greater career advancement opportunities - 26 percent
• Tend to have more training and leadership development opportunities - 19 percent
• Are able to follow a more casual dress code - 15 percent
• Are awarded with trips while other departments are not - 15 percent
