It's been the case for many years that pilot jobs are hard to come by, it's natural that once you've got one you want to hang on to it, and saying no, either to the client or boss certainly isn't easy.
If an employer has a reputation for not holding onto pilots due to Ts & Cs, it would seem logical that after a while the stream of experienced and rated people who will say no will dry up and there's a danger you'll get what your asking for....people around you who are frightened to say no. Not saying that is the case here, in fact this wealthy owner, unlike many, invested in the latest aircraft and had 2 pilot crewing.
