Luddite,
There are some experienced business people of the Pprune Network, who know a great a deal about some of the things you "reveal".
For example
It would not suprize me if some employers are planning to set up shop under a slightly different name having shed their debts.
Standard and routine UK business practice happening thousands of times a year and with companies including household names. In fact one well know football club does about 3 times a season! Some call it flipping, there are many othe names and variations.
In
very general terms when a company goes belly up in the UK, its creditors are ****ed. As others have pointed out, there are processes to reclaim statutory redundancy pay, but it aint gonna be much so don't lose too much sleep if you can't get yer mitts on it.
Best of luck, whatever your beef is, but I think the posters above, like me, are just wise to the realities of business in the UK.
