From the pilot chat this morning: there is no required contract to receive the bonus. It is paid out completely pre-employment. Our chief pilot said today that she doesn't expect retention after receiving the bonus as a problem. I'm here to tell you to take it and leave!
My opinion: if you get an interview and an offer, please take it! Whether you intend to work here or not, it is a free $10,000 because there is no requirement to even pass training to receive it. The company is attempting to bypass our CBA by offering it pre-employment.
