A Metro Council committee will review an ordinance this week that calls for the creation of a tip-line for Metro Government employees to report wrongdoing.Mayor Jerry Abramson says he’s had concerns about establishing a tip-line but will support the ordinance if callers can truly remain anonymous and employees can be protected from frivolous complaints. Both of those shields, he says, are already provided by the city's ethics panel and police tip line."The question becomes, 'What's in between?' And whatever those are that the council wants to respond to, that's fine," he says. "We'll support that effort and see how it works."Councilman Ken Fleming is sponsoring the ordinance, which he says calls for an outside party to operate the tip line, so employees wouldn’t be reporting wrongdoing to a fellow city worker.
