A survey of more than 2,500 employers and managers by recruitment website CareerBuilder.com has identified huge generational differences between Generation Y and their managers.

There was a particular gulf when it came job expectations, the survey found.

Nearly 90% of hiring managers and HR professionals said some or most Generation Y workers felt "entitled" to demand greater compensation, benefits and promotion than older generations.

Nearly three quarters said Generation Y workers expect to be paid more, with six out of 10 demanding more flexible working. More than half employers believed Generation Y workers had a more difficult time taking direction or responding to authority than other generations of workers.

"Generation Y workers are an important segment of the workforce and literally the future of companies and organisations," pointed out Rosemary Haefner, vice president of HR for CareerBuilder.com.

"They grew up in a technology-driven world where standards and norms have changed and often operate under different perspectives than older co-workers.”
