Parents are shying away from confronting their children and leaving all the disciplinary plans to teachers, a survey in Victoria has indicated.

Herald Sun found that the general belief among surveyed teachers is that 75 percent of parents have unreasonable expectations about the school's role in raising kids.

The poll said 75 percent believed "parents expect teachers to provide all the discipline for their children." On the other hand, 67 per cent of teachers said parents supported their authority in the classroom.

Almost half of the respondents had considered resigning over the past 12 months due to stress on the job, the same survey revealed.

The survey of 816 primary and secondary teachers was conducted and analysed by Galaxy Research for the Herald Sun.

An evidence of their skipping parental role in imposing discipline and preventing their children from causing harm is when parents show teachers pages of Facebook status messages with offensive content possibly part of cyber bullying, and they ask teachers to take care of the situation.

Victorian Principals Association president Gabrielle Leigh said students are increasingly likely to be sent to school without learning about discipline from home because parents are more concerned in being friends with their children.

The survey also revealed half of the respondents have been verbally abused by a parent, and three in five teachers say students do not show them enough respect.

Nearly 80 per cent of the respondents said cyber bullying is a problem at their school.

"A lot of parents are reluctant or unable to 'parent' and expect schools to parent for them. We cannot control what happens outside of school hours," a teacher told Herald Sun.

Another teacher said: "On more than five occasions this year, parents have brought in excess of 200 pages of Facebook transcripts and (said), 'We'll leave it to you to sort out'."

"Parents don't monitor their children and expect teachers to 'watch the dog' 24/7."

The parenting style described by Victorian teachers in the survey is called "permissive parenting," a relationship that seals the friendship between friendship and child. In the 1960s, psychologist Diana Baumrind wrote that permissive parents are inclined to respond to arising problems instead of taking steps to prevent an unpleasant situation. Permissive parents, as the Victorian teachers complained, allow considerable self-regulation and avoid confrontation.

Baumrind said children with permissive parents tend to rank low in happiness and self-regulation. They are more likely to experience problems with authority and tend to perform poorly in school.
