As a corporation they are a good company. Benefits, pension and options to purchase Manulife Shares were good.
My personal experience (not applicable to all area's of company, just the area I worked in) is that most management were more focused on looking good than investing in their employees which meant they overcommitted to what could actually be accomplished. The end result was that staff were under high stress to get unmanageable loads of work accomplished. Put multiple teams under this pressure and the work place culture sours as each person is in survival mode.
I am thankful for the experience of working there. I am thankful for the years where my work environment was a good one. Now I am thankful to be searching for a company that will support me in a way that enables me to do amazing work for them.
