Do you consider your job very stressful? If so, you’re not alone — in a recent survey on workplace stress levels, 76% of respondents said stress at work has had a negative impact on their personal relationships, while 66% have lost sleep due to work stress.

But implementing best practices for work-life balance is crucial to getting the best out of employees. While long, demanding hours may give the superficial appearance of productivity, a balanced working style leads to happier, healthier and more impactful employees and can help with talent retention.

In fact, studies show that employees who believe they have good work-life balance work 21% harder than those who don’t. Interestingly, this number doesn’t require employees to actually participate in work-life benefits offered by their employers — but they need to be reassured that the service is there and they can take advantage of it if they need to.

So which companies are hitting it out of the park when it comes to setting an example of good work-life balance? We analyzed Indeed’s 100 million ratings and reviews to identify the companies receiving the highest ratings for helping employees achieve a healthy balance between the personal and professional. Here’s what we found.
