AITA for blocking my SIL from getting a job where I work?

We don't even talk to them (husband's brother and his wife) unless absoloutely unavoidable. In the eight years I've known her she hasn't been able to keep a job more then six months, and has been fired from many of them. She's also a manipulative, toxic person who has a major issue with lying.

Anyway I had told my husband's youngest sister that my work was hiring and that she should apply and I'd get her in (this is a restaurant I'm a delivery driver at, not anything fancy lol). MIL overheard this and relayed this info to other SIL, who dropped off a resume when I wasn't there and used my name.

Boss brought it up and I basically said: "Don't do it, I in no way vouch for her, also her resume is filled with lies and that 'work' reference is her husband's phone number." So her application went in the trash.

However I had mentioned to my boss already my younger sister in law would be applying and she'll need training but she'll be great upfront, and when other SIL came in he'd discussed dates to start training (didn't realize they were't the same person). So when he didn't call her in a few weeks MIL called me and I upfront said that I had told them not to hire her, and also I didn't appreciate MIL extending job offers on my behalf.

Well you would have thought I told her that I'd blocked SIL from getting a job everywhere in a one hundred mile radius. According to her I am cruel, selfish, hate my neice and nephews, etc. They need the money and how will neice have her birthday party next month? SIL hasn't been able to get a job anywhere and she's family so why not give her the chance, etc.. If my husband and I would talk to them we'd see that SIL is trying hard to be a changed person and that I should have given her a chance.

Part of me feels bad now, part of me doesn't. I understand that everyone deserves second chances (my husband is seven years sober), but at the same time I don't want to put *my* job at risk to give her that chance. Selfishly, also, the less time I spend around her the happier I'll be and working with her wouldn't be very conducive to that.

So AITA?
