Sorry We Missed You

I watched the movie “Sorry We Missed You.”.

The main character works as a courier under part time condition. They describe the job as ‘Independent contractor’ and it was in name only. There is even no time for him to go to the bathroom when he is on duty. He can’t rest even if he gets sick. This movie is a warning toward the current society which places too much priority on efficiency.
