In response to "How Can We Improve?"
Would it be useful to identify the exact safety lapse for using lorry to ferry passengers? When we were young, my cousins and I used to travel around on the back of lorry with my uncle, and it wasn’t an issue. If the team can pinpoint the exact safety issue that has led to death/severe injuries, then the team can better propose a few alternatives for companies to consider e.g. (1) switch to bus transportation; (2) bus-pool for workers across various companies; (3) if need to use lorry, can introduce safety measures e.g. seatbelt to secure workers. Also, if lorries are unacceptable, are cargo vans acceptable? This may be useful for the team to analyse further.
