Everything depends on your skillset. Some skillsets such as general office work and hotel and restaurant trades are available in over-abundance and others, such as experienced building trades with all the right paperwork are sought and hard to find. Some, such as film and TV trades, are sitting around waiting for this C19 nonsense to go away so that the starting gun on a thousand dormant projects can be fired. When that happens the employment market will look very different.
There is nothing wrong with firing off 101 CVs to every employer and his dog, but when you do this, research the prospective employer FIRST and talk about them.
Remember the 12 points about writing any letter asking people to buy something or do something.
1. It's all about the employer and what you can do for them. Talk about them and how you admire their company/products/ethic/whatever!
2. Headline. You have two seconds to make your job app stand out before it goes in the bin!
3. One SHORT paragraph on what it's all about at the top. Ten seconds of copy.
4. Keep it simple. Short sentences, short paragraphs and no jargon.
5. Be specific and factual. None of the honest and hardworking nonsense!
6. Appeal to the emotions with words like success and achievement.
7. No gimmicks or gags.
8. Be fulsome. If it takes 1,000 words to explain who and what you are, use 1,000 words.
9. Be honest.
10. Keep it interesting. Boring job apps don't get read!
11. Repeat your call to action such as to call you on the telephone.
12. Give them a logical reason to employ you. Why are you writing and why would it benefit them to employ you!
When you've done all that, test it on as many people as possible. Test, test and test again!
Right now, things look pretty bleak and may get a lot worse - but remember the words of HG Wells - "Today's emergency is tomorrow's joke!"
Good luck! (You're gonna need it!)
