I happened to see an article in the Jan 22nd WSJ "How Companies Secretly Boost Their Glassdoor Ratings" at https://www.wsj.com/articles/companies-manipulate-glassdoor-by-inflating-rankings-and-pressuring-employees-11548171977 (not sure how much you can read if you're not a WSJ subscriber) about some companies pushing their employees to give 5 start reviews in order to pump their score up.
"Last summer, employees of Guaranteed Rate Inc. posted a stream of negative reviews about the mortgage broker on Glassdoor, a company-ratings website.
“An American sweatshop,” read a one-star review in June. “Worst company I ever worked for,” read another in July. The company’s rating on Glassdoor, which is determined by employee feedback, fell to 2.6 stars out of 5.
Concerned that negative reviews could hurt recruiting, Guaranteed Rate CEO Victor Ciardelli instructed his team to enlist employees likely to post positive reviews, said a person familiar with his instructions. In September and October these employees flooded Glassdoor with hundreds of five-star ratings. The company rating now sits at 4.1.
Glassdoor has become an important arbiter of employee sentiment in today’s highly competitive job market. A Wall Street Journal investigation shows it can be manipulated by employers trying to sway opinion in their favor."
I have no idea whether or not AT&T even cares about their Glassdoor review but perhaps it might be worthwhile for people to post a review if they are impacted by all this geolocation/collaboration zone/workspace 2020/no working from home craze. Conversely if you have have good things to say then you should post that also.
