I'm on my third company post-Lilly and now live/work somewhere where I have friends at quite a few other pharma/biotech companies. It's the same everywhere, just look across the CP boards. Jab required everywhere. Lots of DEI talk everywhere. There's no avoiding it.
If you are really bothered by it (I'm not) Lilly is actually better than most companies because of its location. My coworkers in Indy didn't discuss DEI at anything other than optional company events because they knew 1/3 loved it, 1/3 were indifferent, and 1/3 secretly hated it. More people were given vax exceptions, too.
Before you double dip know this - you would die at any other pharma/biotech company (nearly all coastal), other than maybe Abbvie which has similar DNA to Lilly (but a dumpster fire right now). You'd be even more of an outlier. If you want to work in any industry that needs a large educated workforce, this is your new normal.
Suck it up, tune it out, and move on. Nobody is holding a gun to your head. And if you continue to obsess over it, people will start to wonder what team you bat for.
