I have been referred to a site by a few unemployed folks who needed to money to tide them over while they were looking for work. While I rarely endorse sites that offer day work, this site, owned by the National Association of Retail Marketing Services (NARMS) provides a clearinghouse of day, part time and full time work and seems genuine. The merchants that use NARM are legitimate and while the site is very visual (busy) you might want to read through their tabs and learn more about their services.
It is a free site so I signed up to see what it involved. I completed an assessment of my skill set, interests and experiences and then took a look at the jobs listed and the companies looking for help. You can see what is offered without enrolling too.
Many of the jobs involve merchandising/display but there were other listings for positions such as team leaders, assemblers, field service representatives and others.
The site also provides a list of recent job scams (including work at home spam notices) as well as articles and training. I did notice a tab that listed certain types of trainings that you can take for a fee.
From what I have been told, these are not prerequisites for most of the positions. I also learned that like substitute teaching, if a company likes your work, you might be personally requested to come in often.
This site might help those looking for temporary work and perhaps lead to something else. I do know that it will provide a good networking opportunity and the chance to develop new skills and sharpen existing skills.
