American workers don’t use all their vacation days, leaving an estimated 577 million unused days on the table each year. Even when we do get the chance to get away, most of us take our work along for the ride, toting our laptops along and keeping our smartphones glued to our sides.

The 40-hour work week sounds like a pretty relaxing schedule to a lot of employed Americans. In fact, the United States is widely considered to be the most overworked nation in the industrialized world. According to the International Labor Organization, Americans work 137 more hours per year than Japanese workers, 260 more hours per year than British workers, and 499 more hours per year than French workers. The long hours and late nights are only getting longer and later, a problem that impacts our productivity, our health, and our relationships.

Many employers view absenteeism as a large source of loss for an organization and many companies commonly develop specific policies to combat the indirect costs of lost productivity. This common misconception encourages employees to avoid missing work when they’re sick, and often they’re unable to perform at their usual level of efficiency. Recent studies have shown that the combination of health care costs for the employee, coupled with their lack of productivity during the workday, has a far greater effect to an employer than if the individual had simply taken sick days and stayed home. This phenomenon of “presenteeism” is quickly becoming an emerging concern in the workplace.  

Picture a workplace where you and your team are able to be your best selves each and every day. It’s possible, and it doesn’t require a massive human resources initiative or expensive company retreat to achieve. In fact, you can create this culture of optimism yourself, simply by refining your day-to-day thoughts, beliefs and actions to celebrate the bright side of your work, your peers, and your life.

At a recent session of the Aspen Ideas Festival, PepsiCo CEO Indra Nooyi shared her perspective, stating, “I don't think women can have it all.”

This thought-provoking remark is not meant to spark a feud with Sheryl Sandberg and the Lean In movement but rather to contribute to the ongoing dialogue surrounding work-life balance.

With the weather heating up and the Fourth of July just around the corner, we can officially say that the season of company picnics has arrived. While it can be tempting to make things simple and suggest an all-out potluck, we don't think your wellness program would be best-served by a spread of mayonnaise-laden salads, fried chicken and high-calorie desserts.

Coworkers and social networks can play a significant role in the culture of your workplace and the success of your wellness program. Because the majority of us spend the bulk of our waking hours at work, our peers inevitably influence our health. Our coworkers' attitudes towards health screenings, smoking, fitness, nutrition, and flu shots can all affect our own decision-making.

A positive worksite wellness culture can be important for your staff's physical, emotional, and mental well-being.

When your employees’ health is a priority, your workplace becomes more efficient and productive.

The office becomes a place that respects the time, talents, and lives of the individuals who work there, with clearly established roles and responsibilities.

While many wellness programs will brag about ROI and throw seemingly impressive statistics, just creating a culture that values wellness is enough to reduce sick days and health care costs.

Traditional team-building activities tend to send employees heading to the hills.

But we're confident that there are plenty of ways to establish relationships with your coworkers without an awkward icebreaker activity or out-of-place craft project.

Creating those bonds among staff members is about more than just having a cool company culture; employees report that when they have friends at work, their job is more fun, enjoyable, worthwhile, and satisfying.

Now that the weather is warmer, we think there are even more ways you can get employees to participate in creative, engaging activites. Here are eight of our favorite suggestions:
