Yeah I don't disagree, but there is an asymetry. Employers are not walking away from their prior source of income, possibly selling their facilities and preparing to move, etc. with each job offer. And not every offer will be accepted, and yes candidates may leverage multiple offers against each other (or with their current employer) to get better terms. I agree if you accept an offer you should follow through on that. But interviewing to the point of getting an offer, and then declining? Well that's just part of the process. As a candidate, if an employer recinded an accepted offer I would never consider working for them again. And as an employer, if a candidate backed out of an accepted offer, they would never be eligible for hire again.
