mandatory baseball game

I can think of very few professions where this would be acceptable.

I worked at a company that among other things made engines used in F1 racing cars. Located in Indiana. The whole company got the day off for the Indianapolis 500, and the day before the official race ("carburetion day" when they test out & tweak the final car configs). Everyone was highly encouraged to go.

But it still wasn't mandatory and TBH I never went though I kinda wish I had for the experience
