I have been in my job for 15 years - the first 13 of these were working four days a week and the last two years have been working two days a week, and I have also had three maternity leaves and a year of unpaid leave during this time (the unpaid leave following on from my third maternity leave, the unpaid part ending a year ago).
They are now offering voluntary redundancy across the organisation - you can in theory as for a calculation from HR as to what you would be offered but I don't trust HR or my Head of Department so don;t want to ask them this question.
But would my offer be calculated taking into account the years I worked four days a week or would it solely reflect the current two day a week situation - that is, redundancy pay is a certain multiplication of your monthly salary, but my monthly salary now is vastly reduced compared to what it was for the first 13 years of my job.
Thanks
