Pros
Working at Safeway provided regular working hours and extra cash. My boss was fairly flexible with scheduling. The light and ambiance in not unpleasant. Coworkers were friendly enough. Music wasn't horrible, though a bit repetitive. Learned how to use a cash register. Very good thorough training program, though not all the skills learned were implemented by management in practice.
Kontras
Long hours on your feet, with minimal breaks. Not really treated like an individual, just another drone to do your job. Lifting heavy items is tiring. All of the movement and physical labor is in one direction, which puts an uneven strain on your back. Lots of the bagging equipment was at an inconvenient height. Training suggested certain standards in customer service that were not effectively taught and implemented in practice. Very repetitive, not intellectually stimulating. Ideas for improvement were not encouraged. I believe there were unfair wages discrepancies based upon gender.
