While laws such as the Fair Work Act (FW) and the Occupational Health and Safety Act impose many legal obligations on the employer, the worker has very few obligations. Nor can there be evidence of the terms of employment agreed upon without a written employment contract. Who is the employer? What`s the beginning? What are the agreed timetables? Where is the work done? Who is the employee talking to? What is the amount of compensation agreed upon? How many redundancies does an employee have to give you if they want to resign? These are all fundamental questions that are easy to answer from the start with a written employment contract. Choosing the right type of employment contract is a sensitive issue. There is no magic solution “One size fits everyone.” The employment contract must carefully reflect the agreement between you and your employee. Before you begin development, you should consider whether the role is covered by a bonus or enterprise agreement. Is the role offered full-time, part-time or casual? Is the role for a fixed period or a specific project? There are more than 100 industrial and professional awards that cover most of the people who work in Australia. This means that many employees who are not covered by an agreement are most likely covered by a bonus. The collective agreement is signed between an employer and a representative union in a company or industry. The agreement between workers` representatives, i.e. trade union officials and employers, is subject to the condition of ratification by workers. All employees are covered by the NES, whether or not they have signed a contract. A contract cannot make workers worse than their minimum rights.
All workers working in Australia are automatically covered by the NES, whether or not they sign an employment contract. By May 2004, AEAs had achieved coverage of about 2.4% of the workforce.  Mining companies have advanced the agreements with some success and have offered substantial wage increases to workers who have opted for an AWA. According to OAS statistics, as of 31 December 2004, 1,410,900 people were covered by EU-certified agreements, 168,500 by non-unionised agreements and 421,800 and more than 21% by A.A. respectively. As of December 31, 2005, there were 1,618,200 under the Union Certified Agreements, 185,300 under non-union agreements and 538,200 Australian enterprise agreements.  Figures published in March 2005 by the Australian Bureau of Statistics show that hourly wages for workers in AWAs were 2% lower than workers` hourly wages in registered collective agreements, which were mainly negotiated by trade unions.  For women, AEAs paid 11% less per hour than collective agreements.  An Australian Labour Agreement (AWA) was a kind of formal agreement negotiated between an employer and a worker in Australia that existed from 1996 to 2009.
