A group of cyber-security experts is urging companies to set up a way for people to report their workers behaving abusively online.
Lisa Forte, of Red Goat Cyber Security, says she has received unsolicited explicit content from official accounts on LinkedIn and violent threats on Twitter and Instagram.
"It can feel like the platforms do nothing, the police don't do a lot, lawyers are expensive and the publicity legal action generates can be negative.
"We're not saying a company is liable for the behaviour but it will be able to decide the most appropriate way to deal with it - which may be offering support rather than disciplinary.
Ms Forte's co-founder, Rik Ferguson, from Trend Micro, said many companies had anti-bullying policies but they tended to focus on internal behaviour.
"If you know your organisation has made that commitment, it may make you think twice about doing it," Mr Ferguson said.
