Labor supply and demand especially, decrease, elements, increase, example

prav_Cfa7

I have been hard time remembering elements which affects labor supply and demand. I know there are three factors price of the output, supplement and complements affects demand, and substitution and income effect affects supply. But, i get confused when I try to increase and decrease these various factors. Could someone provide me a real world example how they are correlated, especially I get confused in supplement and complement, or probably a way to remembering this.
