Employee burnout and stress is a big problem in the average American workplace, but it's especially true among some of the country's biggest tech companies, many of which have famously rigorous workplace cultures  that often encourage long hoursfavor young people, and sometimes require unreasonably high levels of productivity.

Blind, a message board app created for employees to e surveyed more than 11,000 employees at 30 of the biggest tech companies to find out just how many of them feel burnt out by their work.

Users were asked the simple question, "Are you currently suffering from job burnout?" and could only answer with either "Yes" or "No," according to a Blind spokesperson.

Blind's findings show that overall, more than half (57.16%, to be exact) of tech employees surveyed said they were feeling burnt out by their jobs.

Each participant's employment status is self-reported, and while the results do not include the opinions of every employee at each of the companies listed, they give us an inside look at the workplace cultures experienced by those who did respond to the survey.

Here's how each of the biggest tech companies stack up, based on their respective levels of employee burnout:

In a statement provided to Business Insider, a Credit Karma spokesperson pointed out that their internal surveys measuring employee burnout have shown different results. Here's Credit Karma's full statement:

In our most recent anonymous employee survey, more than 90% of employees told us that their workload was in line with or exceeded their expectations. We appreciate the efforts to bring this important issue to light but question the results as an accurate snapshot given the small sample and questionable methods used to identify a current employee of any of the companies mentioned.
