So I work at a company of three with a known massively under my value salary (recent grad, project I want to work on, responsibility I can get nowhere else). I'm obviously always looking at what I could get if we went under or I wanted to leave for an unforseen reason; I find it very hard to work out what I'm equivalent to. By asking for a salary and an email to see what different titles go for it makes it impossible for me to work out where I stand. - and I'm also curious about what we need to offer our next hire (ie what should be expect to get for our money)
