A new job everyday

One aspect of our society which is now commonplace is to see people alongside the road [everywhere you go] advertising their services as painters, tilers, builders and a variety of other 'professions'. While this is considered by many to be a nuisance, I can't help but look at the flipside -

- everyday, each of these people effectively looks for a new job, with a different employer, a different location, and a different wage/salary.

When last did you change jobs? I recall seeing that changing jobs fell into four of the most stressful events of a person's life [along with getting married, death of a close relative and moving house]. The most difficult part of changing jobs is not necessarily once you know where you're going, but all the uncertainty when you're still looking.

Now imagine looking for a new job every single day.

Here's a thought - in a each neighbourhood, establish a central venue where all such skilled people can go daily, register as available, and possibly even receive a meal. Their details [name, ID number, skills, contact number, etc] would be recorded here. Any people looking for workers with these skills could go straight to this 'agency' and find a tradesman with the skills they are looking for.

It may take a while to become readily accepted, but could provide huge benefits to both sides, including:
For the tradesman: a central destination each day, possibly a meal, credibility through verification of their details, and keeping them away from potential danger at busy street corners and intersections.
For the public: a central source of skills when required, verified details of the individual you're employing and more safety in public areas that work-seekers currently frequent.

This kind of idea would probably require government initiative, but with a bit of creative flair, could also prove to be a profitable business. How? Sale of advertising to a captive market each day; visibility through sponsorship of food, tools, etc; commission on people placed; revenue from transport facilities going directly to/from the venue. These are just off the top of my head - I'm sure there are endless possibilities.

Perhaps it sounds a bit ridiculous. Perhaps it could work.
