Pros
I worked at Lilly for several years but recently decided that I needed to inform others of the inner workings of how abusive and harrassing behavior is swept under the rug to keep projects on track.
Cons
I was a direct witness to a campaign of retaliation and harrassment that was ignored by senior management. A manager was extremely hostile to their staff members and eventually received an HR complaint. These complaints are confidential - however this manager shared the complaint with their staff in an effort to identify the individual that submitted it. Their staff then began to "investigate" the matter and started harrassing likely suspects. This culmulated in an off-campus encounter where a Jewish employee was targeted with anti-semetic language and had a drink poured on them - with a threat of "we know what you did and we're watching you." This event was widely known to management, but no action was taking because the manager was in a critical project role.
