The employees claims for wages and holiday pay are treated as preferential claims. they will be paid before unsecured creditors.
The bad news is that it may take some time to sort this out. I have only just had my claim sorted out from the company i was with, that went bust in September 2001.
In the mean time, if there is no cash just now, there is a government fund that the administrators will give out the claim forms for. this will take a few months to pay out and it is capped at something like £230 per week claimed.
As I emember, they will pay this for any notice in leu etc, so you shold be able to claim 3 months notice at £230/week + outstanding pay and holiday pay. All at £230 per week, or what ever it is now.
The rest will probably take years.
Good luck guys, keep your chin up, You will get through this.
