Well "do they" is the wrong question and "can they" is the right question.
(The question is not what you want it to be, but what was asked) If you learned to "read for comprehension" you would see that I answer the "do they" questio
n while providing some perspective as to when they "do."
By the way, there is no "implied promise." They have a written, signed and notarized contract.
No court has ever (hmmm, Forget the training contract its illegal...) held a training contract to be invalid due to Constitutional, federal, state or local laws. Lastly, I have consulted (in the past) with a lawyer about training contracts and she gave me all of the information I have given you.
Now, who is promoting beliefs here? I gave absolute facts, if you think they are just beliefs and thus are fallable, why don't you post some information to disprove what I have stated?
Here is your goal:
1. Prove that a training contract at Flex Jet is not signed and notaraized;
2. Prove that a court has held that a training contract similar to Flex Jet's was held to be unConstitutional or in violation of federal, state, or local laws;
3. Prove tht Flex Jet
never 
attempts to collect on training contracts.
Your move.
PS....If anyone is planning on signing a contract with
the intent of violating that contracting...do some soul searching or go sell used cars.
