This is a tough edit! Can you spot it and let me know what it is?

"You really only have one option when it comes to being annoyed by a fellow employee," says Donna Flagg, president of The Krysalis Group, a business and management consulting firm in New York City. "Simply let your co-worker know how you feel and politely ask them if they would mind curtailing their annoying habit."

Wow! Edit not so tough, bluediamond. You win, and the points will be awarded to you sometime this weekend.

The error here is by:
"Simply let your co-worker know how you feel and politely ask them if they would mind curtailing their annoying habit."

it should be:
"Simply let your co-worker know how you feel and politely ask him if he would mind curtailing his annoying habit."

"You really have ONLY one option when it comes to being annoyed by a fellow employee," says Donna Flagg, president of The Krysalis Group, a business and management consulting firm in New York City. "Simply let your co-worker know how you feel and politely ask HIM (HER) to curtail HIS (HER) annoying habit."

MISPLACED MODIFIER: The word 'ONLY' should modify 'one', not 'have.' The second sentence uses plural pronouns for the singular 'co-worker.'

I'm not sure if I'm catching everything, but I do know that in the sentence "Simply let your co-worker.....ask them...they..."
a "co-worker" is a single subject, however "them" and "they" are plural pronouns. "Them" and "they" should be "he" or "she" and "his" or "her".

Simply let your co-worker know how you feel and politely ask them if they would mind curtailing their annoying habit."

There is a problem with the use of them, they & their. "Simply let your co-worker know how you feel & politely ask (TAKE OUT THEM & put in him or her). That is all that I can see.

"... Simply let your co-worker know how you feel and politely ask him if he would mind curtailing his annoying habit."

or

'...Simply let your co-worker know how you feel and request that he curtail his annoying habit."

Co-worker is singular, so it should be something along the lines of "...politely ask him if he would mind curtailing his annoying habit."

though I still don't know what you're asking.

Did Donna Flagg really say that? She made TWO grammatical errors, at least.
