I'm a founding engineer at a startup and just found out that the founders have concealed an investment from me leaving me with a potential tax bill on $10,000s of income that I had not received. I did my best to keep my story within 2000 words but I couldn't shorten it anymore without leaving off important details so I posted the full text here: http://pastebin.com/xLLNUF0H I feel so disgusted and cheated right now. I had worked for this company for almost 3 years doing everything possible to maximize its chance of success: from working overtime to meet deadlines to answering support emails on weekends, and now I find out that they've kept this investment (and the tax implications that go along with it) hidden from me for over a year. I'm left thinking that they concealed it so they wouldn't have to give me a raise, but I am more concerned about the tax implications of these shares. I had to leave work early yesterday when I found out about this and I don't think I'll be able to come in to work today. What should I do? Should I confront the founders about this? Is there any use in contacting a lawyer?
