Your employees are the most productive when they're motivated to do great work. But according to a study from the American Psychological Association, 63 percent of U.S. adults experience boredom on a regular basis -- including in the workplace.

Not only are bored employees less likely to contribute-- they're also more likely to seek out new job opportunities. A study from online learning platform Udemy found that bored employees are two times more likely to leave their companies.

Is your team putting in effort to ensure employees-- especially top performers-- don't get bored? I've outlined a few tips below to keep employees focused and decrease the likelihood of boredom.

1. Give employees more responsibility.

Some employees get bored on the job simply because tasks and responsibilities that were once challenging are no longer challenging enough. So to keep employees excited about coming to work every day, it's important to continuously challenge all employees and give them new responsibilities.

In the same Udemy study referenced above, 80 percent of employees surveyed indicated that learning new skills would keep them more engaged. Encourage employees to seek out professional development-- such as courses, conferences, and more-- to continue learning and reach the next level in their careers.

Also consider making their work more challenging by either setting higher goals or delegating more strategic projects. Employees will appreciate that you trust them with more responsibility and by focusing on increased responsibility, they'll be less likely to get bored.

2. Break up employees' routines.

Even for employees who love their jobs, following the same routine every day can get monotonous and lead to boredom. And while each employee's day-to-day work is key to your company's success, it can also be beneficial to push employees to step away from their routines.

At my company of about 200 employees, most have a few bigger projects they're expected to complete each quarter. These projects offer employees the opportunity to complete work that is different from their daily responsibilities. These projects are also intended to address issues the company is facing, and by completing the projects, each employee is contributing to helping the company move forward and grow.

Ultimately through quarterly projects, employees face a new challenge each quarter and feel like they're truly making an impact on the business, which keeps employees engaged and less likely to face boredom.

3. Encourage employees to try different roles.

Some employees might be bored or disengaged simply because they're great for your team but in the wrong role. If this is the case, you can increase engagement by suggesting the employee transitions roles or teams.

When employees switch roles, this term is known across many companies as "internal mobility." And while 87 percent of companies believe that internal mobility programs would definitely help with retention, only one-third have these programs in place, according to a study by FutureStep, a recruitment software provider.

At my company, we've had employees move from the sales to the product team, from the customer success to the operations team and more. In most cases, these transitions work out better in the long haul both for the individual employees and the company as a whole.

By creating a culture where employees don't hesitate to transition roles when they're more passionate about a different area of the business, you can keep these employees from getting bored and boost productivity as a result.

Bored employees can pose a significant risk to your business. By following the tips outlined above and making a concerted effort to curb employee boredom, you can keep your excited about being on your team for the long haul.
