No one can say what your parole officer WILL do. It is almost certain that SOMEONE from the company or organization will be called periodically to verify employment and performance. If your employer does not already know about your parole status, you might consider telling them. If this is a one time deal which requires only 6-7 days of travel one time only, then the odds are diminished that they might have to call and verify much.
You can also talk with your parole officer about her plans with regards to communicating to your employer. If she can verify your employment and activity through some other means, she may not have to speak to your employer.
Ultimately, what she will do is anyone's guess.
