When a coworker asks you to lie, chances are it's to avoid getting in hot water with the boss for something they did—or didn't do. Since you don't want to get a reputation as a liar or appear to be a partner in crime—both of which could jeopardize your job— the goal of this script is to make clear to your peer that you won't lie, without coming off as condescending or holier‐than‐thou. Basically, you're walking a tight rope between maintaining good relations with your coworker and your supervisor. If this is the first time the coworker has asked for your “help” you can lean a little to her side of the tightrope. If this is clearly a habitual problem lean toward your supervisor's side. But if this incident falls somewhere between unique and habitual you'll have to try to strike a balance.
