I have read the article a second time to try and understand why you would make a statement that Delta wants "to oblige crew members to be on call on their scheduled layovers" and found no reference or inference to your claim. I'm not writing this to oppose your opinion or upset you, but to set the record straight about what the article actually reports. I believe in impartial journalism...that is... reporting without interjecting personal emotions or bias.
When I post on a board such as this I really try my best to stick to the facts and not try to influence others about how I may feel personally or sway people in any particular direction. I feel that if I give respect to others, I'll receive it in return.
