How your boss could be screwing you up!

It is difficult to be an employee - you are either working overtime without any extra pay or you are underemployed and struggling to get more shifts.

The revelation was made by a new report from The Australia Institute, which claims that both problems are caused by the casualisation of the workforce.

According to news.com.au, employer groups however have claimed of increasingly insecure working conditions are overstated.

The report found millions of employees are not paid for the extra hours they work, and the number of people working overtime is rising, which causes stress and anxiety, the report said.

The survey found that there is a significant increase in the number of employees working unpaid overtime in the past five years.

In 2013, 60 percent of workers said they are not paid for the extra hours they work, compared to 45 percent in 2009.

The report found that nearly 24 percent people would like to work more hours, compared to 28 percent who want to work fewer hours.

Report author Prue Cameron said the increase in casual and non-permanent work is putting pressure on people to work harder for longer, and to work more hours unpaid.

Cameron said that there was a mismatch between the demands of the workplace and what is achievable in normal working hours, the report added.
