Consider that my opinion is weighed based on the Christmas season as this is the busiest time of the year. As such, experience may vary depending on location and season. This review reflects the "delivery agent" role.
Work days were typically 12 hours on most days, which means completely engaged both physically and mentally at all times. After training, you are left to your own resources. Collating ad-mail and organizing mail can take the novice upwards to 4 hours to complete, which includes scanning of all material; parcels and registered mail and loading into vehicles. You are sent out to new neighbourhoods each day in unknown areas left to figure the route to yourself. Time becomes a significant commodity. Supreme organization and quick thinking is a huge asset. You are not to bring back any undelivered items. You deliver in all weather, in night or day.
You are relocated on the daily to different Depots. Having a vehicle is an asset. I take public transit and spent 4 hours each day commuting to and from work on top of 12 hour days. I gave myself 5 min lunch breaks on route to save time to complete as much during daylight, to come home as early as I can. You are only with coworkers during the depot at the beginning of your day.
Management is political. Heavy union presence. Changes per depot. Mgmt will not take Kindly to excuses on undelivered mail, regardless of skill or lack of knowledge.
ok pay, lots of chances for OT especially on busy seasons: time + 1/2 after 8 hrs, dbl time after 10 hrs. could be done shift in 5 hours, paid for 8 on slow periods
lack of personal life on busy seasons, physically enduring and repetitive, lots of commuting, on road in all conditions etc.
