In VS of

[Allieso]

I've seen quite many example sentences with in which I usually think: why not 'of'.
"The strike laid the groundwork for an increase in wages."


My question is.. 'in' in the sentence above makes more sense than of ?

Yes.

I don't know if it makes more sense, but that's the usage. People will look at you funny if you use "of" in that setting. English is filled with little quirks like that.
