Request Letter to Office Workers for Feedback

Dear Co-workers,

If you have time this week, I'd really appreciate if you can read my draft on the technical documentation. They are 30 pages in total. I really want and need your feedback.

Thank you,
Marge

None of your Business Letter

Dear Colleague,

Perhaps you should keep your mouth shut. I would prefer you rather not tell everyone about my private matters. This is none of your business.

Up Yours,

Co-Worker
