Thanks for the answers!
I am trying to load some files on all workers, but I am not sure how to do it properly.
Considering the example in the first post, I changed the contents of ParallelTest.jl to:
__precompile__(false)
module ParallelTest
using Distributed
@everywhere using Pkg
@everywhere Pkg.activate(".")
@everywhere include("$(@__DIR__)/parallel.jl")
@everywhere using .PMod
greet() = print("Hello World!")
end # module
and added another file parallel.jl in the src directory containting:
module PMod
println("loaded")
end # module PMod
I managed to load the module successfully, but I get redefinition warnings for the module loaded in parallel.

I also tried to use using .PMod instead of @everywhere using .PMod, but I get a LoadError saying that PMod is not defined. I think that the problem is that on the workers it’s in the global scope, while on the master process is inside a module.
