they are doing by the book and we're putting them under the dress
From the TV series 'Suits' Season1, Pilot episode.
What does "put someone under the dress" mean here?
I googled it but I couldn't find any useful website or information.
The phrase they used isn't "under the dress", but "under duress". Duress means "force or threats used to make someone do something", and it's usually used with "under" as in someone being made to do something under duress. So the character is saying "We are threatening them in order to make them do what we want."
The line can be found in the script here.
