Want a career with benefits? The finance and tech industries have the best employee benefits on average, a new study from review site Glassdoor found. The retail and food services sectors offer the worst benefits on average, the study revealed.

Despite the rise in "sharing economy" jobs — which often do not offer benefits — nearly 60 percent of job seekers rank benefits and perks among top considerations before accepting a job, according to an earlier study by Glassdoor, which conducts research on job-market trends.

For the study, Glassdoor looked at a sample of almost half a million benefits reviews posted by employees on its site over a 15-month period (June 2014 to September 2015). Reviewers rated benefits on a 1 to 5 star scale, with 5 stars representing high satisfaction.

Researchers focused on eight industries: business services, education, finance, health care, information technology, retail, manufacturing and restaurants and food services. The firm looked at overall benefits ratings, and broke out three categories: parental leave, 401(k) plans and free lunch and snacks.

Overall, the finance, IT and manufacturing sectors earned the best ratings with 3.72, 3.68 and 3.64 stars, respectively. When companies are competing for workers or strong unions are involved, benefits get a boost, said Glassdoor chief economist Andrew Chamberlain. At the other end, the retail and food services sectors offered the poorest benefits packages. They garnered 3.11 and 2.73 stars, respectively.

"Even when benefits are offered in those industries, they are low quality — a double whammy for workers in restaurants and retail," said Chamberlain.

"Workers who have the most access to benefits and the best benefits are always those with the best bargaining power," he said. "Software engineers or certain quantitative people in finance, for example."

One example is cloud company Salesforce (NYSE: CRM), which was named the top company employees want to work at by job listings site Indeed. It offers all the usual health and financial benefits and takes it one step further by throwing in wellness benefits. The goal is to boost employee engagement — meaning involvement, enthusiasm and commitment — and to fend off competitors looking to woo top talent, said Jody Kohner, vice president of employee engagement at Salesforce.

Across all industries, employee engagement has hit crisis levels, according to a Gallup report published in January. Just 32 percent of U.S. employees are engaged. Worldwide, the figure drops to 13 percent.
