They included incidents of verbal abuse and aggressive language towards staff from customers at public facilities.
A council spokesperson said incidents also included visitors to aquatic facilities ignoring lifeguard instructions, breaking rules, littering and damaging property.
“Over the past few months, staff have been encouraged to report incidents to help the council understand patterns and identify areas needing attention.”
McGrath said politicians often copped abuse, but staff out on the street should be left alone to do their jobs.
“I haven’t experienced it, but I know some elected members in the past have.”
He said he liked getting out in the community and most people were great.
“It’s our job not to hide and I’m always happy to answer questions and chat.
“In fact, my kids stopped coming out with me years ago because a 10-minute trip often turned into an hour.”
A council spokesperson said it had hired a training provider to help staff manage challenging interactions.
“This training equips staff with practical techniques to manage challenging or confrontational behaviour safely and effectively, including knowing when it is appropriate to step away from a situation.
“The training is tailored to each facility, addressing the specific situations staff are most likely to encounter in their day-to-day work.”
McGrath said the council fully supported its staff.
“This behaviour is unacceptable, and those responsible should be aware that it could lead to serious consequences, including prosecution.”
