I worked as an intern for a large multinational company for about 9 months. It was not a difficult job. I exceeded what was required of me, worked weekends and even built a prototype reports website for them. At the end of my service, I was not retained and have moved on.
Recently, I got a request from one of my colleagues to help out the department, I did help him against my better judgment. Then he came with another request to help out the department.
I made it clear to him that I will not work for a multinational company whilst I am not a staff. He begged me for 3 days saying it was important to the department and they needed my skills.
I thought it was all over but I was contacted by another person in another department to help out with some work and told him no.
How should I handle a company that I no longer work for when they request more work, but don't offer to pay me?
