Human Factors; Procedure
On my recent rotation; I was coerced into a 14 hour crew day by [Crew Scheduling] et al.The departure time was XC:24 from ZZZ; which should have resulted in a XA:54 show time and a 10 hour crew day; according to the Operations Manual. Instead; I received an email informing me that if I did not agree to a one-hour reduced show time; [Crew Scheduling] would unilaterally change the departure time to XC:00; thereby forcing a 14 hour crew day by virtue of a 6 minute change in show time. I have heard from others that their show or departure times were similarly adjusted up to 30 minutes using this same underhanded tactic. Thus; this is a commonly used way to extend crew day for company convenience. Clearly; the resulting level of fatigue does not matter.The original illegal day's schedule was posted several days in advance. I naively assumed that it was an oversight and would be corrected. Instead; I learned about how much The Company is really concerned about crew fatigue. My responses to [Crew Scheduling] and the Chief Pilot were ignored; and the show time was moved without comment. I flew the last leg under protest.What is the point of publishing Flight Operations Manual reduced duty hours for early show times if [the company] can arbitrarily change them for its own convenience; without regard for the resulting fatigue effects? Why does [the company] make us sit through hours of [training] about fatigue; risk management; and safety when the company clearly has so little regard for any of those issues?What about the impact on the client? Instead of following the rules; [Crew Scheduling] set itself up for a crisis had I justifiably called fatigued after the end of the ten hour legal crew day.If management is not going to respect the fatigue effects of early departures; I suggest that the appropriate portions of the FOM (Flight Operations Manual) be removed so that pilots clearly understand The Company's true fatigue policy. For now; I will consider myself warned that [the company] does not actually care about fatigue issues and the associated safety issues; and will proceed accordingly.[Crew Scheduling] should prohibit changing of show or departure times to extend crew day. Once a trip is booked for XC:29 or earlier; the crew is limited to a ten hour day; and the company should not change it.
CE750 pilot reported that their company does not follow policies to prevent excessive fatigue on long duty days.
