Ms Thompson, who is also a school principal, has taken time off work and believes the Victorian Education Department should do more to support its staff.
"There was no help from [the] regional network leader, really, other than to say they were sorry about it," Ms Thompson said.
Evan Hughes, the principal of Willmott Park Primary School in Craigieburn, worked with Mr Thompson and said he would like to see more support for principals.
"The vast majority of parents are fine and they respect the school and respect the role of the principal in the school," he said.
"But there's always that rogue family or rogue parents that just won't let an issue go and just pursue the principal and pursue the teaching staff or the administration."
Ms Podbury agreed it was a demanding job and said she wanted the Victorian Government to spend money on resilience training for principals.
"This is a tough job and it can push people to the very edge — and, as we've now seen, completely over the edge," she said.
"[The Victorian Government] is aware that this is a big problem and I think they struggle to respond appropriately to it. But they are prepared to work with us and listen."
WorkSafe Victoria said it could not provide details about individual claims.
The Victorian Education Department said it took the health and wellbeing of staff "very seriously" and provided a range of services to principals.
A spokesman added support was being continually improved.
