If the company I currently work for is looking to outsource a website to an outside contractor. Would it be possible/ethical/legal for me to apply to that company to intentionally work on this website (ignore time constraints of working on both)?
Would it then be possible/ethical/legal to bill both my current company and the contractor for the time spent on this project?
Since, as mentioned in the comments, it may be double billing. Would it be ethical to not charge them both for doing the work, but still work separately at both places? Would that be considered as me being something like a mole by working at the contractor company?
