There are alot of things flying around here so to speak. What needs to be established is who was right and then the comapny needs to support that person. and be non-forgiving with the wrong person. if this is a reccuring problem perhaps they should implement a system whereby if crew (fd or cc) refuse to fly whilst the flight (after investigation) could have been conducted safely and legally, there S&T should be withheld for any aditional night/day stops. they could even go further and say that when a crew refuses to fly with grounds that are found to be not satisfactory, then they are responsible for any additional traveling costs.
harsh i know but something needs to be done. clearly!
