People get laid off all the time ( like what just happened to me), but people have to be adaptable with multiple skills ( like me ) so they can work else where.
In the modern era, nobody has a job for life. I was lucky as I was only unemployed for only one day and I am have gone back to commercial pool plumbing with a company I worked for previously for 12 years. That work may well end as well has it has previously. Apart from my 9.5 years in the RAAF, I have worked in the construction industry and as you know, the resource sector (gas).
But I know that there is no such thing as permanent employment, so I make hay while the sun shines.
