In our organisation I'm sure they would have said getting a pilot to do the post maintenance ground run or flight, they seemed to run for the doors or come up with some excuse, I'm waiting for a phone call was always well used. Me, I jumped at the chance as it got one away from crew room politics. If it needs any explanation pilots were staff and subject to a yearly appraisal for a pay rise, politics ruled, helping maintenance was not some thing on managements radar.
