Whats a $5000 bonus after tax?...about $2500, right?
When is it paid?...after you complete the sim and IOE, right?
What happens if the union is able to overturn the bonus before your paid? Bye bye bonus

Reality check guys...afterall, you could loose the value of the $2500 in the first year because we have no cancelation pay. Just go to a company that is honest about their pay upfront and doesnt try to play tricks to fool you.
