Steady membership fees and cost savings helped fuel Costco (COST) to record membership renewal rates this year, driven in part by concerns about inflation.

But the Issaquah, Washington–based company has quietly emerged as a leader on another critical issue that dominated the retail sector in 2022 — labor relations and the employee push to unionize.

Rival retailers, meanwhile. have struggled to address employee demands for higher wages and better benefits while fending off efforts to organize. But Costco, Yahoo Finance's 2022 Company of the Year, has managed to separate itself from the pack, building on a reputation as one of the friendliest places to work in retail.

According to data from Glassdoor, Costco employees rated the company a 4 out of 5, putting it well ahead of competitors like Sam’s Club and Target (TGT). Longtime CEO Craig Jelinek earned an approval rating of 85% from its staff, surpassing Amazon’s (AMZN) Andy Jassy and Walmart's (WMT) Doug McMillon.

“They’ve set a higher entry-level wage, more full-time jobs, more access to employee benefits, and generally, probably better working conditions as well,” said William Brucher, an assistant teaching professor of labor studies and employment relations at Rutgers University. “A lot of that has to do with Costco’s business model, in that it makes most of its profit on memberships.”

That base annual $60 membership fee has taken the pressure off of Costco to be a “low-road employer” according to Brucher, who said the discount retailer has consistently outpaced competitors when it comes to the number of full-time employees it hires. Costco cashiers earn, on average, $32,000 a year. While just one-fifth of hourly workers at Costco are unionized, they earn largely the same pay as their non-unionized workforce.

In addition, employees who work for 180 consecutive days for more than 23 hours a week qualify for Costco’s health benefits plan, which includes medical care along with coverage for dental and vision with low co-pays, according to Glassdoor.
