Once. It was awful.
It was early on in the financial crash & recession of 2009. I was pregnant with my second child, and my then H was at risk of redundancy too (which happened, albeit eventually 2 years later).
I loved my job. They had never before made redundancies & handled it terribly.
It really affected my life, in that it created a whole set more problems that made my abusive marriage worse.
I was fortunate in that I found work and kept working easily enough after - but in short-term contracts which while professionally relevant, weren't at the same level.
Between that, more DC & marriage breakdown, it took me a very long time to work my way back to a secure & appropriate level job. I never take my job security for granted and it's always a consideration when I think about future career plans
The film Up in the Air, with George Clooney, came out shortly after this happened. I went to see it not quite realising - one part has people expressing feelings / reactions from people who were genuinely made redundant. It was so close to the bone. I just started crying in the cinema!
I'll never forget how traumatic it felt, even if overall, I've probably ended up in a sector & role I'm more suited to.
