Yep that's just a side-effect that some employers look at.They don't look at the reasons why someone left a job: All they see is a list on a CV which suggests they can't settle or hold down a job.This isn't a personal attack on anyone, it's just one more way for employers to find out who the best candidate is.
Option 2 "or", you give me 3 option, 1st true, 2nd or 3rd false, therefore I chose "or", ha ha I am so coool, hey did you get the job yet?
