The Environmental Protection Agency's (EPA) internal watchdog has found that top agency officials retaliated against three staffers for expressing different scientific opinions. The employees who were victims of this alleged retaliation thought chemicals should be considered more toxic, while top officials sought to consider them safer, according to the reports from the EPA's inspector general. EPA scientist Sarah Gallagher says she thought the agency should consider the chemical as toxic to fetal development, while another official wanted to classify it as a lower-priority body weight issue. In another case documented in a report finding retaliation against scientist Martin Phillips, a senior science adviser allegedly changed an assessment in a way that removed "reproductive toxicity" as a concern from safety information that goes to people who work with the chemical. In a third report finding retaliation against scientist William Irwin, a manager also allegedly tried to remove evidence of reproductive toxicity. These instances appeared to have a chilling effect that could impact other agency scientists' willingness to stand up to management. "Other assessors noticed how those who disagreed with management were perceived," the reports said. They added that a person whose name was redacted testified that disagreeing or delaying the resolution of backlogged cases could cause management to label an employee "problematic."
