I have name changed because I could be recognised in RL and by the employee I think is no good.
A new friend of mine mentioned to me that someone is going to work for her soon. This person has also worked for me and has been, in all honesty, useless. Basically if she didn't feel like coming into work she didn't and took 3 weeks off at a moment's notice leaving me in the lurch. When here she was ok at the job but we have had much better people in the past.
My friend told me this person is going to work for her but didn't ask me what she was like.
So should I tell her anyway or would that be wrong? The person will be working with her children.
