Pros
The benefits and vacation structure are great, and for most of the business areas there is a great work-life balance available for the majority of employees. Compensation is generally in-line with the industry, but varies highly depending on your manager and business unit. The majority of peers and co-workers are very friendly and there's a good sense of team.
Cons
The company's larger corporate organization in Canada is extremely stable and consistent. However, the US organization has seen a great deal of uncertainty, strategic direction shifts, and reductions in business lines over the past several years. Future direction and stability in the US is extremely uncertain, and clear communication from senior management is non-existent. The US organization thrives on form over substance, and opportunities do not exist for hard-working, honest, and talented employees. The most talented team members are singled-out and minimized by managers that do not understand the subject matter or responsibilities of the teams they are managing. Who you know is definitely more important than what you know. Hence all the other reviews here describing that the most talented people leave. (this is absolutely accurate) If you're looking for punching the clock and low demands on your time and skills, this might be a great fit. But if you're looking for challenging and rewarding work, Sun Life might not be the place for you.
