I am new to the software industry, having worked in the manufacturing field before now. Currently I work on a project which is almost 50% completed, which means I have to grasp the technology faster and make my efforts be useful for the project as I am a contractor.
Recently, a colleague at the office was discussing a technology with which I had good experience, so I joined the chat. The next day he called for a meeting with his team, which I attended. Since then, there have been a few email exchanges and meetings every now and then. Since it all started unofficially, I didn't think about informing my immediate supervisor about my involvement in the project.
Now, how should I go about with this ? I really want to help my colleague, but not at the cost of my job.
