Redundancy Looming

The business I am working for has gone into administration, therefor all our stores will be closing and within time all the staff will be made redundant. I have been with the business for sixteen years, and although I know I won’t get a penny from the business, I will be able to claim in back through the government.

Sadly we don’t know when the stores are closing, so are finding it hard to plan ahead. Ideally I want to start looking for a job now, but I also really don’t want to loose sixteen years worth of redundancy and no lack of notice payment. We are also a really close nit team, so although I owe the business nothing, I really wouldn’t want to let my team down or leave them in the lurch.

I then had an idea... If I was to accept a new job, I know I could also continue to work for the original business part time until the store closes. My question is, if I did do this, could I still work for both jobs and still claim the redundancy? Or would the redundancy claim become void because I now have another job?

Any help would be appreciated
