If you're on holiday, you are going to love this contest: photographing people who are doing manual labour. In other words, people doing work by hand. Examples could be fruit picking, building a house, cutting a tree, ...
There can be only one person in the picture, and it's allowed for that person to use a tool for the work. The tool is not a requirement, labour such as fruit picking, building a house or cutting a tree, are also considered on-theme. Important is that it has to be physical labour and not mental labour. So a person typing on a computer is not considered on-theme
So get searching and find the hardest working person who is completely caught up in the work he/she is doing
To get some inspiration, have a look at this contest on Pxleyes: here
