Hi Oktawia and welcome to the forums. "The labour market is tight (or loose)" is a bit like saying "vegetables are expensive". Tightness/looseness is about supply and demand, and unemployment levels are only part of the equation. People who are in work but looking for a move or willing to move are also part of the supply part of the equation. The UK has a long standing tradition of job mobility compared to a country like France (where people are, traditionally, less willing to move), so in that respect the UK labour supply market is more fluid/loose than the French one.
Equally, some segments of the market have a large available pool of labour - waste collection, for example, where the job can be learned in a matter of hours. Compare this with airline pilots and brain surgeons where supply is not high, and has a lead time of several years schooling/training. In this respect the brain surgeon market is much tighter.
Geographically, markets can be very different - heavy demand for taxi drivers in big cities, but not on small islands.
Take these principles and try to develop a few more examples and variations.
All the best
Ray

Hi Ray
I would like to use part of your reply as a quote "The labour market is tight (or loose)" is a bit like saying "vegetables are expensive". Tightness/looseness is about supply and demand, and unemployment levels are only part of the equation" would you be okay with this? if yes what is your surname so I can reference it properly?

PS the students on the MBA course in international HR on whkch I teach regularly quote 2 other remarks

"There is no such thing as 'best' practice', only 'context-relevant' practice" AND (more obviously) "context is king"

Thank you Ray I am currently studying my level 5 CIPD HR course. I have saved the other quotes in case I can use them :)

You're more than welcome Julie, and good luck with your level 5s

This is really helpful as I am also on the same question!

In reply to Ray:

Dear Ray, may I also quote you as part of my CIPD Level 5 qualification? This really does encapsulate the variety of considerations that need to be taken when looking at this subject.

I was taught that the Labour Market is the area from which applicants are recruited....this true? :)

Thank you for this, very interesting.
