Texans don't just work hard, they work harder than almost anyone else in the nation, according to a new study.

Just in time for Labor Day, WalletHub has revealed the hardest-working states for 2019, and Texas lands at No. 4, meaning only three states — North Dakota, Alaska, and South Dakota — work harder. To determine the ranking, the personal finance site reviewed a host of factors, from average workweek, commute time, and leisure time to employment rates and the share of workers with multiple jobs.

In Texas, where 96 percent of the labor force has a job, workers stay on the clock an average of 40 hours a week. While that might seem pretty standard, somehow, that makes us the state with the fourth-longest workweek.

And those hardworking Texans could use a break. Surprisingly, 29 percent of the state's workers don’t use all of their vacation time. One contributing factor could be the state's high percentage of engaged workers (35 percent), described in the study as “involved in, enthusiastic about, and committed to their work and workplace.”

As we know, work doesn’t just start and end at your desk. WalletHub also measured workers’ commute times, volunteer hours, and leisure time, which it categorized as indirect work factors.

In Texas, workers regularly travel about 26 minutes one way for their jobs, and despite their long workweeks, they make time to volunteer for 27 hours each year on average. In regards to work-life balance, Texans set aside almost six hours a day for leisure time. That may sound ample, but workers in 19 other states spend even more time relaxing.

This isn't the only recent study to call attention to how much time Texans spend on the clock.

A recent report from mobile technology company Kisi named Houston, where workers clock 43.7 hours a week, the second most overworked city in the U.S., second only to Washington, D.C. Austin also shot to the top of the list, with workers laboring 43.5 hours a week, followed by San Antonio (43.1 hours) and Dallas (42.9 hours).
