"I don't want to make more work for you"

[goodname]

Hello,

I work with several people who's main language is Spanish. I communicate with them mostly in Spanish, but need some help translating a concept.

I am trying to say that I don't want to make more difficult work for them.

In English, I would say, "I am not trying to create more work for you".

My current translation is "No tratando hacer más trabajo para ustedes."

My work position oversees theirs. Would that be misconstrued as me saying I don't want them to work there?

I already put a letter in their workplace including that phrase, so I need to find out if I need to get the letter before they start working so they don't misunderstand.

Thank you,

Ryan
