If he was told to come back in six months do it. I am sure it was the Cog, as if you dorked up the Psyche you are done. That has never changed.
As for what they may or may not do, it is conjure. There is no hiring dept, there are not employees of a hiring dept, and legal has no department to make a ruling for, ergo there is no way to know the answers to the questions you are asking. It is that simple.
When there is the above, legal will make their decision, and then we will have something to discuss. It has to be this way due to lots of guys that would sue for a job. It does not make sense, but it is what it is, and yes, DAL has been sued. Not the best way to get a job.
