Union representing WestJet mechanics issue strike notice in time for busy travel weekend

For the second time in just over a week, travel plans for thousands of Canadians are in jeopardy. With contract talks stalled, WestJet's unionized mechanics have again issued a 72-hour strike notice -- which puts them in a legal strike position early Friday morning. As Andrea Macpherson reports, the airline has responded by saying it will "lock out" those workers.
