My references for the last 3 jobs over 6 years has been "Yes, he was employed here from $startdate to $enddate as $jobtitle"
And that's it, to avoid any risk of there being any liability issue.
It's gone from "you're not allowed to give a negative reference" to "why bother doing anything more than the bare minimum" in a number of industries I've been in.
IMO, as a manager, you're an AH if you aren't willing to give more information than that in a reference check, regardless of company policy.
Ask me for a reference on a good former employee: you get a lot more than dates and titles. This is where I'd be an ass to not talk about them more. I don't walk around afraid of my own shadow.
Ask me for a reference on a poor former employee: you get dates and titles.
EDIT: just noticed that you expect former managers to risk their job to provide a positive reference for you, despite the fact that you left them. I'd gladly write recommendations on former employees linkedin profiles if requested, but when my former employee's new employer is contacting my employer (via me) for a reference, I'm not risking my job for theirs, and I don't think that makes me an AH. If they do, I've sorely misjudged them.
The backchannel reference check is already blown, make no mistake.
It's a firing. You're now, instead of being entitled to benefits (in most areas) or being able to negotiate for them, being given absolutely nothing.
Also, a mutual non-disparagement agreement and severance is extremely easy to negotiate for.
And then guess what? Instead of being fucked in that backchannel reference check, _everyone_ takes pause due to the potential consequences.
Sure, a backchannel reference check might still happen, but if and when you find out about it: good night.
Pardon me for being dense, but can you unpack that figure of speech at the end?
