Too late.
> * recently we dismissed developer after discovering he was working (also full time) at another company (we coordinated termination on both sides - I'm not even sure if it made him without work or just removed 2 out of N jobs)
You should expect a lawsuit for this. If you give me his contact, I know a few good lawyers.
Really, who cares? If they're getting their job done, who are you to tell another man what he can do with his body?
