Some pros, several cons, and still very much carries the '1.0' mindset...
Pros
Middle management is a dedicated team committed to building a great place to work. With an aging workforce, opportunities are becoming increasingly plentiful. Also, TELUS is a great place to see the evolution of technology roadmaps.
Cons
An older workforce also brings an older mindset. Innovation from newer team members is sometimes stymied because of old ways of thought. A lot of roadblocks (corporate beaurocracy) in place to bringing an idea to life. Although middle management is a great team, communication up to senior levels is difficult. With a company as large as TELUS, speed to market can lack. Team members are often 'told' and not engaged in developing solutions to issues. Office facilities / work environment can also be terrible, depending on which building you work in.
