Here's a nice sob story, thoughts and advice please 
I left a steady if unspectacular job last November 2012 to start work with a company which was due to launch a new piece of software in January 2013. It was a big risk but there was the chance for a big step forward in my career, as well as offering lots of flexibility in working hours which was really appealing to me - I could spend a lot more time with the kids and it gave my wife the chance to push her career forward a bit as she'd been tied up with the kids pretty much full time up to then. So after much deliberation I took the plunge.
The software was being developed by a guy in the USA and soon after I started it became clear that this was nowhere near ready and I expressed my doubts that it would ever be. As time went on I continued to express my concern that this was never going to get finished, and sure enough finally the penny dropped that this developer was struggling badly with the project. Once we started pushing him he eventually quit due to 'ill health' in May.
As expected, the work he's done so far is useless so we've gathered some quotes to get this done properly by a reputable company in the UK and once funding is in place for this we will be going again, with a view to launching in Q2 2014.
The company is basically just me and my boss. He's a really good bloke, albeit somewhat naive, and he's been doing all he can to keep paying my salary. Although it was pretty obvious to me from the first day I started that this US developer was not going to deliver, he believed the constant "It'll be ready in 2 weeks" etc etc that he was being told, and the investment he already had in place has dwindled to nothing.
Last month he was unable to pay me, but he was awaiting a further investment which would keep us going for the medium term. This has yet to materialise, and we are now approaching the second month without pay, so I appreciate I really need to get another job, and I'm firing off applications every day. I've since discovered that my boss had to borrow money to pay my previous month's salary and he's living hand-to-mouth himself at the moment.
Apparently this further funding has been agreed, and money is 'on it's way' but I'm obviously dubious after what has happened up to now. I know he's not just making this up, I met with a representative of the group that are investing and have spoken to him on a few occasions since. I'm party to the emails that are going back and forth and all the noises are that the money is imminent, but this has been the case for over a month now.
The problem I have is that the project, if we ever get it going, is an excellent one and if it is done correctly (which I feel it will be now I'm involved) will be extremely lucrative. As I've been on board from a very early stage I'll have a very good role within the business, which I'm never going to get elsewhere.
So I'm not sure what to do - I don't want to quit acrimoniously and if I do I will be missing out on what is potentially a great step forward in my career, but I can't keep waiting for my wages, I have a family to feed, and I need my salary from last month to pay back money I've borrowed to keep going.
What do I do?
