Yesterday I was handed 4 weeks notice that my hours of employment will go: from 30.5 hrs per week to 16 hours per week and my position to go from permanent, part-time (PPT) to casual. I work as an Administration / Officer Manager in the Manufacturing Industry. In order to have my facts in order before any further discussions with my employer I would like to know if the following applies: As an employee older than 45 and having worked for this company for 15 years, an extra weeks notice is required. Both employer and employee have to agree to any changes in hours. Since 2010, I am not eligible for any pay increase. Many thanks for your time.
