Experts have warned that you are likely to lose you job if you fail to report people who send you inappropriate emails at work.
Porn was still the most common type of offensive material being sent around office computers, said Joydeep Hor, from management firm People and Culture Strategies.
Rude emails that undermine the reputation of managers or co-workers and the accidental "reply-all" email are also common problems, he stated.
"I just find it extraordinary people don't think records are going to be kept and they're not going to be caught out," News.com.au quoted Hor as saying.
"I often joke my favourite defence proffered by an individual in trouble for distributing porn is 'I don't understand why I'm in trouble, I don't discriminate against anyone - I sent the email to everyone I work with,''' he stated.
A NSW solicitor told News Ltd he represented a man who was fired for receiving a pornographic email from a co-worker but failing to report it.
"This idiot started sending him emails. He hadn't looked at it and he deleted most of them - but he didn't report it," he said.
The solicitor said the man received compensation after he sued for unfair dismissal, but he did not get his job back.
Jade Muir, a 30-year-old business analyst from Perth, said she was disciplined for accidentally sending her boss an email that had been intended for her secret office boyfriend.
"My then boyfriend and I were at the pub together and my boss drove by in a car. The next day I sent an email to him (the boyfriend) saying we should be careful not to be seen together and she (the boss) replied 'was this meant for me?'" Muir said.
"I had to have a meeting with HR and my boss," she revealed.
She was later informed she was not allowed to email or speak to her boyfriend while at work.
According to Catherine Davidson, a conflict management consultant, 80 per cent of her workplace mediations contained references to inappropriate work emails or social media posts.
She said many of these occurred outside of work hours when people were affected by alcohol or distracted by "relaxed'' environments.
"People forget to draw the line around work behaviour and sometimes they use forms of communication outside of work hours forgetting the same conditions apply," she said.
