flew as part of his day job would have been run through the company monitoring system, which is actively scans for breaches of SOPs, "gate" busting etc.......
This was a factor in a fatal accident of a pilot I had trained for a contract. He flew very well when monitored (operator on board at all times). The very first flight he flew solo, to bring the plane back to me at the end of that project, he decided to flew as he wanted, and literally killed himself with carelessness within ten minutes of taking off. No one minded his choosing to deviate from the norm a little while solo, but everyone was totally unhappy about the fatal outcome.
I have noticed that pilots who fly "supervised" may explore extra freedom when flying in a different (or differently/not supervised) operation.
