This review of the impact of the microelectronic revolution on the Canadian telephone industry focuses on the prospect of dwindling job security for telephone workers. Technical advances that are cited as having reduced the industry's job market include the dial telephone, direct distance dialing, directory assistance computerization, and interactive television directories. Also discussed at length are the effects of two computer operated switchboard systems, Traffic Operator Position Systems (TOPS) and Traffic Service Position System (TSPS), as well as the effects of electronic switching, digital technology, and the attachment of subscriber provided terminal equipment to the telephone network. The paper concludes with the warning that any further introduction of technological innovations must be well-planned or else industrial chaos and turmoil among Canadian organized labor will result.
