Why is it that companies deliberately set out to have bad industrial relations and complain when they get it ? The loss of goodwill from the pilots is far more significant then the minor cost saving of a cup of tea or coffee.
A happy pilot will be motivated to save the company money, ie requesting track shortening or a more favourable runway, trying to get flight levels closer to the optimum, and what if they urgently need you on a day off ?
A disgruntled pilot may just follow the flight plan as given, not bother requesting a more suitable runway or better flight level. If rostering call on a day off, well there's no need to be contactable is there ?
Potentially hundreds of $$$$ of good will lost for a saving of a few cents.
Are you sure? - 10 hour flights on easyjet? - where?
Probably refers to duty days, with reporting time, flight times and turnarounds, time at work can easily exceed 10 hours.
