MORE than 60 Brisbane City Council employees have been caught out by the ethical standards unit.

Their offences range from illegal dumping and misusing council equipment to downloading porn, impersonating a police officer and painting an unauthorised clearway.

More than 110 complaints of unethical behaviour were investigated by Brisbane City Council's ethical standards unit last financial year, according to documents obtained by The Courier-Mail under Right to Information legislation.

Of those, 65 cases were substantiated and about 11 are still under investigation.

In 11 cases, workers had their employment terminated, while nine employees resigned, 25 were warned and a further 20 received a final warning.

In one of the more serious cases, a council employee was caught impersonating a police officer. He was charged over the incident and resigned.

A council truck driver lost his job and was charged with drink-driving after he struck three parked cars, while another was sacked after he was found to have accessed pornographic and drug-related websites.

The ethical standards unit also substantiated a complaint that during construction of a sports field, employees and a private contractor were illegally dumping waste while other officers were given beer to turn a blind eye.

Another council employee was sacked after he painted double yellow lines in an unauthorised spot and a community regulation officer was found to have falsified the number of infringement notices that had been issued.

An employee who was found to have instructed a labour hire worker to use council machinery and materials to build his personal driveway resigned, while another caught on video-sharing website YouTube igniting fireworks was warned.

Another group of council officers were given formal warnings after they were reported for spending three hours playing cards on the roadside.

A final warning was given to a bus driver who was found to have verbally abused a cyclist before swerving to hit the rider with the bus and driving off. A colleague received a formal warning after it was found he made racist comments towards schoolchildren. Several other council officers were found to have downloaded pirated material and pornography.

Deputy Mayor Adrian Schrinner said he was disappointed the actions of a minority had tainted the reputation of council employees.

"Brisbane City Council has more than 9000 employees who provide an outstanding public service, but these actions are unacceptable," he said.

"Council takes a harsh view of code of conduct breaches and that is why a handful of staff have had their employment terminated, others have been given formal warnings and some have resigned."
