While Shashank has received 100% approval by its reviewers, the CEO of India's biggest e-commerce firm Bansal has got an approval rating of 94%, US-based said.

Recently, Flipkart rolled out a range of employee-friendly initiative including extension of maternity leave to 24 weeks. Under the current labour laws, companies can give a maternity leave of up to 12 weeks.

The Bengaluru-based Flipkart is probably the first online retailer to introduce such measures to create an attractive work environment for female employees.

"Companies with high ratings tend to have engaged and motivated employees who believe in the company's mission, feel that their job matters, and feel they have career opportunities to advance within their organization," The Economic Times quoted, Scott Dobroski, career trends analyst, Glassdoor, as saying.

In contrast, Bhavish Aggarwal, CEO of taxi aggregator Olacabs and Vijay Sekhar Sharma, founder of mobile payment services firm Paytm, do not seem to be too popular among their employees. Ola's Aggarwal and Paytm's Sharma have got approval rating of 70% and 69% respectively.

"For big companies, it would have been good to have an option for employees to rate the entire management team, as it gives a more holistic view," Nirupama V G, MD of recruitment firm Ad Astra Consultants, told TOI.

"But for startups, the ratings are a true reflection, because the CEO is the manager, he is always in touch with his employees and is hands on," she added.

In IT sector, Infosys' CEO Vishal Sikka has earned the highest rating of 95%, followed by Cognizant's Francisco D'Souza with a 94% approval rating.

The rating for TCS's CEO N Chandrasekharan and Wipro's CEO T K Kurien stood at 84% and 74% respectively.
