Most people are compensated based on one of three things 1) an hourly wage 2) monthly salary 3) piece rate/commission. The wages earned as a result of these are called "gross wages". From the gross wage taxes and other deductions are subtracted. Examples are FICA, Medicaid, Social Security, and State taxes. Other deductions may include union dues, uniform service, parking, etc. What is left over is called "net wages". This is the amount you will receive in your paycheck.
Your question refers to "using trade unions and diagrams". Unfortunately this system doesn't allow graphics to be inserted. The closest I found to a wage diagram was one from the Australian government that discussed whether or not taxes should be deducted from a salary. law.ato.gov.au
As to "using trade unions", the only relationship I am aware of is that of wage agreements as a result of collective bargaining. This is where the union negotiates a wage scale based on some factors agreeable to both the union and the business.
