a shortage of truck drivers means that once containers arrive at destinations, it will become more difficult

In addition, in Europe and the United States, a shortage of truck drivers means that once containers arrive at destinations, it will become more difficult. The COVID-19 pandemic led to the closure of the port, further aggravating traffic jams. The shortage of truck drivers in the UK was particularly acute, in part because EU workers left the UK after Brexit and due to the pandemic. Coupled with tax changes, drivers coming from other regions of Europe faced higher working cost or employment cost for working in the UK.
