Despite their avowed opposition to the strike no one was willing from among the dozens of nonunion workers to cross the picket line.
What about the sentence? Is it Ok?

Despite their avowed opposition to the strike, no one (from) among the dozens of nonunion workers was willing to cross the picket line.

Actually, I didn’t notice that I’d omitted “from”. Yes, I think it’s optional here. I don’t see any need for it, but I wouldn’t say it’s actually wrong to include it.
