I spent quite a few years working for a company unionized under the Communications Workers of America (700,000 members). Neither of these claims were true then or are true now. A specific job title would have a wage tied to the agreement, that increased based on years in the title and other negotiated increases. There were absolutely performance bonuses... as per the agreement, not at the whim of management. Management gets to set a wide scope of performance requirements, and those he cannot meet them lose their jobs. What I do see is that unions do a good job at preventing arbitrary abuses by management... and management really hates that. *per friends who still work there
