Four Houston energy and chemical giants have just landed on Forbes' new ranking of "America's Best Employers for Company Culture." The report highlights six more Houston-area companies for their inspiring company culture.

Forbes partnered with market research firm Statista to survey over 218,000 workers at companies with at least 1,000 employees throughout the U.S, and relied on data from the past three years of employee surveys (with an emphasis on the most recent data and recommendations from current employees). Companies don't pay to be included, Forbes additionally noted.

Among the final list of 600 U.S. companies, 30 Texas employers were praised for providing "a unifying company culture that inspires a sense of purpose and loyalty among employees."

The Houston employers in the energy and chemical sector are:

• No. 325 – BP
• No. 492 – Chevron Phillips Chemical
• No. 558 – NRG Energy
• No. 593 – LyondellBassell

According to the report's research, employers with a successful company culture don't rely on "surface-level perks" such as free lunches, wellness apps, and flex days to inspire employee engagement. Instead, employers that focused on conflict resolution and coaching their managers saw a reduction in employee burnout and an increase in "perceptions of fairness and leadership care."

"In fact, the researchers noted that when 'senior leaders changed how they led — how they ran meetings, gave feedback, made decisions and responded to challenge — trust scores rose by an average of 26 percent,'" the report said.

The six other Houston-area companies that earned national acclaim for their company culture are:

• No. 15 — Houston Methodist
• No. 47 — MD Anderson
• No. 220 – Stewart Info Services
• No. 332 – Baylor College of Medicine
• No. 525 – Insperity
• No. 586 – Waste Management
