The 50 best places to work in 2019, according to employees

• If you're looking for a new job, you might want to check out companies where employees are happier than the norm.
• Glassdoor has released its annual ranking of the best places to work, which takes into account its database of 45 million company reviews provided by anonymous current and former workers.
• Tech companies dominated the listing, but plenty of firms in healthcare, consulting, manufacturing, and food got kudos for their excellent workplace cultures.

The average American spends some 90,000 hours at work during their lifetime, but 80% are outright dissatisfied with their work.

For that overwhelming majority, the secret to job satisfaction might just be a new company. Glassdoor, a job site with 45 million company reviews, has just released its annual Employees' Choice Awards for the Best Places to Work.

The rankings are compiled from anonymous employee feedback that former or current workers can provide right on Glassdoor. To compile the listing, Glassdoor scans their massive database of company reviews.

Workers writing a company review are asked to assess the pros and cons of working at the company, growth opportunities, compensation and benefits, culture and values, senior management, work/life balance, if they would recommend the workplace to a friend, and the company's six-month business outlook.

Those reviews are compiled in Glassdoor's awards algorithm, which also assesses the quality of reviews represented in its ranking.

Then, companies receive a score on a scale of one to five - five being the highest. The scores have been rounded to the nearest tenth in our article, while Glassdoor ranked the companies by looking at their score rounded to the thousandth. The employers on this list scored between 4.2 and 4.6 on Glassdoor; the average company rating is 3.4.

Many of these companies in the list of large US workplaces (having more than 1,000 employees) are Bay Area tech firms. Of the 100 workplaces, 23 have headquarters in San Francisco, and 29 are in tech.

That's because tech firms are facing a major labor shortage and are keen to woo employees with excellent work cultures, Glassdoor chief economist Dr. Andrew Chamberlain told Business Insider.

But you don't have to be a techie to enjoy the benefits of an excellent workplace, which often includes mission-driven company cultures, smart coworkers, transparent senior leadership, great compensation and benefits, and work-life balance.

"To work at a company that treats you ethically and gives you good pay and benefits, you don't necessarily have to be in tech," Chamberlain said. "There's something for everybody."

What's more, you don't even need to be in an office job or to have a college degree to work at a company that will treat you right. In-N-Out Burger, Trader Joe's, lululemon, and other employers powered by associates all topped the list, as well as healthcare providers that are largely staffed by nursing assistants and similar roles.

Here is a countdown of the best 50 workplaces, along with their headquarters location, a description of the company from Glassdoor, and a quote from a current or former employee. You can see all 100 companies on Glassdoor.
