Earthworks... Dispute with the occupational disability insurance

(with us there was a difference of over €6,000 between the main contractor earthworks and the alternative, which we could not use due to interface coordination, etc.)

Was your main contractor also against you awarding it separately, or did you decide against it yourselves?

Was your general contractor also against you awarding it individually, or did you decide against it yourselves?

What does "against" mean? An adult or businessman would not say: I am against it?!
How was his behavior? How did he argue?

Was your general contractor also against awarding it separately or did you decide against it yourselves?

The issue was a bit more complicated for us because only the floor stripping was problematic, and this was only recognized after it had already started. And since we were inexperienced, we let ourselves get stressed and continued working with the general contractor instead of taking the time to reconsider it calmly.
