According to Business Insider the employee was assigned to fieldwork for Project Wing, which is X’s program to create delivery drones for transporting consumer goods and emergency medicine.
While out in private ranch lands in the Central Valley in California one day, the employee succumbed to either a heart attack or a grand mal seizure because of the hot temperatures in the Central Valley, coupled with a gruelling work schedule of 10-12 hours a day and stress may have brought it on.
The Project Wing drone tester, who returned to work after two months’ leave, found himself demoted and sent back into a field gig before eventually being pushed out of the company.
According to Business Insider, some members of the Project Wing field team painted an alarming picture of hostile work conditions driven by engineers and managers back at headquarters who scheduled the group to conduct loads of tests, thereby producing loads of data, despite the long hours outdoors that such a schedule required.
To make matters worse all their demanding work and data was being ignored because their backgrounds in the military were allegedly viewed disdainfully by Google X.
