I work for Zim in the U.S. how concerned should we be that the doors would close and we would all be out of jobs?
This is my advice
I think anyone working for any shipping company should be concerned at this time.
Not just a matter of the company closing, but those that do survive will most certainly be cutting staff.
If I were working for a container carrier, I would start quietly looking at other types of companies, perhaps someone involved with RFID, which ties in nicely with shipping.
