I'm going to explain: I'm a freelancer who collaborates with a couple of companies.
Because of reasons, that I don't know, one of them lost a client1 and I would like to contact them by myself, as a freelance, because I like the project. But before doing any step, for fairness, I told the company's proprietor what I wanted to do and she said it is ok, but I should give to her a 40% fee on the amount of my earning.
Another time, with another company, I found this situation with a colleague of mine and she had not been asked to acknowledge any "fee".
I'm not stealing any contact or project, I just want to find this person by myself and to have a direct "interview" as a freelance, I would work the project outside of the time dedicated to the company and I have no contract which states something similar...
So, to me, there is no reason she could ask me this.
In sum, I am profiting of the fact that a client found my name2 linked to the site of a company3 but then they decided to not work with them and I would like to contact them as a freelancer.
How should I handle the situation?
1 Where I would have been the only worker.
2 With my whole knowledge, they are the reason for which they decided to contact the company.
3 And they (the client) have thought I was one of their employees.
