Filing I-485 with Former Employer

[norwood21]

I have an approved I-140 (not withdrawn) from a former employer PD March'10. I moved to current employer in Dec ’10(7th year extension) who has not initiated my GC as yet .I'd like to get I-485 filed by former employer(since PD is current) and work for them in good faith.I know that GC is for future employment but in view of the recent RFEs /random denials:

1. If I-485 filed by former employer is denied by USCIS -will it end my case completely- or can current employer initiate GC filing afresh and still capture the earlier I-140 PD (despite earlier denial of I-485)?
   
2. Is it common nowadays to receive an RFE for filing I-485 with fomer employer ? Appreciate any sharing of expereinces.

I havent heard of getting an RFE because you file with fomer employer. What is your source of this information?

I have a similar case as yours PD March'10 with former employer.
