> 10x more productive on my side business
Pretty sure the answer is here :)
Quite. On the face of it: possible career faux pas.
I own (with two other folk) my own little company and hire other people. I actively encourage my troops to have a bash but I suspect that a firm like AMZ would have differing views about what used to be called moonlighting. Mind you we only turnover a bit over £1M and that is loose change down the back of a sofa for AMZ ...
