<human>: Can you succinctly summarize the text in 1-3 sentences?

Background: Alice (31F) and I (30F) have known each other for 12 years. We met at orientation, had the same major, were flatmates from our second year onwards, went to the same school for our masters, were basically best friends since we met. She is an absolutely terrific friend, loyal and kind and smart. After we finished our masters, we were recruited by the same organisation. We worked there for 2 years and then she moved out of the country to do similar work elsewhere while I continued to work in the same organisation and rose through the ranks to the point that now I have considerable influence on who is hired.

Current Problem: Alice and I have stayed in touch through skype and regular holidays together. I was her MoH and she was mine. Now her husband has been posted back to the city I live in and has moved here while she wraps things up before moving back as well. 

Obviously I was psyched about having my best friend back in town, until last week when she called and asked me to recommend her for a position in the organisation where I work. It would help a lot in her relocation process. If I did so, she would definitely be hired. And here's the problem. 

While Alice is a terrific human being and a fantastic friend, she is a bit of a disaster of an employee. She doesn't meet deadlines, doesn't take her work very seriously, a lot of her work has been shoddy to the point that she has missed multiple promotions. Though she is in another country, we are still in the same field and I've met a lot of her coworkers and bosses, and they've all said the same thing. If I recommend her and her work is not up to mark, it's my name and reputation on the line

How do I break it to my best friend that, while I love her, I will not recommend her for a job she desperately needs because I don't want to compromise my professional reputation because of her lack of work ethic and still keep our friendship intact?
<bot>: My best friend is not good at her work and if I recommend her for a job, it'll hurt my professional standing. Is there a way to break this to her without destroying our friendship?
