(NEWSER) – UPS drivers left work for 90 minutes to protest the firing of a colleague—and found themselves in hot water not long afterward, the company tells the New York Daily News. Twenty were fired Monday, while 230 were told they had their jobs only until replacements were trained. A rep for UPS says the Queens, NY, drivers knew the protest put their jobs at risk. The drivers were demonstrating following the dismissal of union activist Jairo Reyes, who'd worked for the company for 24 years, local union head Tim Sylvester tells the paper. They believed he hadn't been treated as "innocent until proven guilty," the Queens Chronicle reports.
