Sorry Foxgolfer but how are the 2 things the same? I thought the bill was to look to address the sort of situation that was happening in a large scale in British Gas / Centrica. Fire and Rehire is not the same as replacing employees with different employees. Was there any apparent intent for P&O to rehire? You seem to accept that that there wasn't.
As far as I was aware what P&O did was not in accordance with current UK employment law (and, yes, I am aware that there are questions around the jurisdiction covering employment in this case). The fact that P&O continue to be a going concern makes their process & the execution of it reprehensible irrespective of questions of recent financial performance or the impact of COVID, inflation etc.
