Hi Phil
I've been in a similar position after redundancy as a shift workers at a factory making plastic injection automotive mould products and made applying for jobs my job "working" 8 hrs day at the Job Centre job club where they provided me with advice, stamps, envelopes, helping with cv's etc.
One other avenue that hasn't been mentioned and was my way out and back into work was giving my CV to numerous job agencies. I was amazed at how many still offered jobs well after getting back into work.My first job through one agency was driving around the region replenishing soaps in commercial premises toilets, mats, etc . It was an income, kept me busy and met people.I then moved up to better and better jobs through various agencies one if which was for Nissan at Tyne Dock earning excellent money driving cars into car parks, off the mothership.Unfortunately my type 1 diabetes put paid to that job when I hypoed at work when adapting to a new shift pattern and I was gutted. Another job came through an agency which I stayed at for 6 yrs until my present job came along where I've been for over 10 yrs in a very busy car bodyshop.
I strongly recommend joining some job agencies and sending them your cv.They get paid by the employer to get you in the door so do their best to help you. ..both you and the agency benefit and many can become permanent.
Don't give up. If I was closer I'd pop round.
You'll likely have to do jobs you haven't done before.I started in sales, retrained in retail management, plastic injection moulding,cnc machining,and finally nvq level 3 in bodyshop parts control.
These days you can email your cv to agencies from the iob club.Spend time on your cv and help if needed from the job club to try to get your cv to stand out with what you can do for a potential employer and make your age work in your favour from experiences that you have gained and always put how quickly you can learn new skills, how good you can work individually or as part of a team and how you look forward to a challenge.
Always relate your cv covering letter to evidence of what you've done to relate to that job.
I really wish you the best of luck and kick all those youngsters with less experience to touch with your new found go!!
