Ok so I have only been flying corporate for the last nine years and have had on occasion pressure to fly in bad weather and said no , and never had any problems there after . As the pilot in command you have a legal responsibility for the safety and well being of the passengers and crew even if one of them is you're boss !
If one of my employers decided they no longer wanted my services that's fine but if I was dropped over a single incidence where I would not fly due weather then I would have grounds to take legal action. What might be helpful is a standard employment contract from the caa for freelances to use when working in the corporate environment to clearly state to the employer who has final say with wether to fly or not .
