That's terrible! I suppose sometimes things backfire, no matter how good our intentions are.
What happened?
They tried to make out I was bad at my job, that's the last time I'll give somebody a heads up at my own expense again.
Oh, no. That's awful! Did you report something that had occurred at your job? 
I sure did, thankfully I've been there a lot longer so they know me well enough.
Yeah, that's good. It's hard to know whether to blow the whistle sometimes. It could always come back for you. I'm glad that it sounds like it worked out.
It did, but it could have ended very badly for me or even have resulted in me losing my job.
Yeah, navigating those sorts of things is treacherous, but as long as you know you're doing the right thing, that's all you can do.
