If your out of work and looking for a job your most likely depressed, I was when I was unable to continue my shopping habits after the company I worked for shut down. You have most likely already looked at and/or completely used up most of the job posting websites. Sites like Jobsite, Monster, total jobs, and jobs24 can all be great resources but eventually still not giving you the results you require. Have you looked at trying out the more niche websites? There are websites around that cater to all of those other specific industries.
For instance, I came across a website the other day that did searches on security industry related jobs. I mean, if you’re interested in doing anything within the security sector its worth a shot right? The site is called https://www.cross-deck.co.uk , they seem pretty good at what they do and have a vast database of jobs available. The had a very informative landing page that I hit when I found the result on google, and it educated me on the training and positions they had.
