The gender pay gap doesn’t appear to be getting much better in general, and in one industry in particular, it’s awful, new research from employment review company Glassdoor finds.

A study based on 534,000 anonymously shared employee salaries have found that the pay gap in computer programming is the worst, with men making 28.3 percent more than their female colleagues on average for the same job, according to a Glassdoor statement.

Within that field, scientific and mainframe computer coders had the greatest gender difference.

There were also big pay gaps in other tech fields, which has long been criticized for being a “boys’ club” that is often exclusionary of women. Male video game artists are typically paid 15.8 percent more than women, and there is a 14.7 percent pay game in information security specialists.

But it’s not just the tech world. Male chefs are also paid a lot more than women, at about a 28.1 percent clip — not far off coders. And there was a similar pay gap for dentists and senior executives.

Researchers think that there remains a significant workplace bias against women, particularly in traditionally male-dominated fields. In addition, men are often making the decisions about pay and promotion in male-dominated fields, perpetuating the cycle.

There is good news in some areas in terms of pay parity. Event coordinators were paid about the same, with men making just 0.2 percent more than women, and there is a 0.5 percent pay gap for therapists and business coordinators.

“In the U.S., men earn on average 24.1 percent higher base pay than women in Glassdoor salaries. That amounts to women earning about 76 cents per dollar earned by men,” the statement reads. “However, once we compare workers with similar age, education and years of experience, that gap shrinks to 19.2 percent. Going further, when we compare workers with the same job title, employer and location, the U.S. gender pay gap is about 5.4 percent.

“That amounts to women earning about 94.6 cents per dollar earned by men,” the statement continues. “At today’s real median earnings for full-time working women of $39,621, that is a pay loss of $2,140 per year or more than $64,100 over a 30-year career. For those who earn more than median wage, they could be losing a lot more each year. For example, if a woman earns $100,000 per year, she loses about $5,400 per year or more than $160,000 over the course of a 30-year career.”
