You have been offered redundancy. Take it. Its your legal right. Everyone who takes redundancy, or who knows its coming (after all, you're supposed to get notice and even be given time to look for a new job) -or even suspects its coming looks for a new job.
And dont forget in the new job you have to start off fresh on your accumulated years in case they make you redundant.
I've made people redundant, given them their money and they got jobs immediately elsewhere, and I was delighted for them. In fact I often made sure they got jobs before giving them redundancy, though it's more difficult nowadays.
Revenue does not care that you will immediately start a new job, but there are Revenue implications in some redundancy situations as explained on several previous threads by cleverer people than me.
