The irony is that the French employees haven't been sacked, because they are protected by EU employment laws.
The employees' union, RMT, was staunchly in favour of Brexit.
Before the referendum, the union wrote:
"Environmental regulations, employment rights, food safety, privacy laws and many other safeguards will aslo be secondary to the rights of corporations to make even bigger profits ...
The EU has promoted undercutting and social dumping leading to the decimation of UK seafarers ...
The EU is developing a new policy framework to attack trade union rights, collective bargaining, job protections and wages ..."
The RMT members were duped. The RMT leadership and anybody else who claims they voted Brexit to protect British workers should be hanging their head in shame. The likes of Rees-Mogg and Sunak knew very well why they were in favour of Brexit and had good reasons (for them). Their success was to con those who had much to lose.
DP World does have the money to keep the jobs, but it wants to increase profits and diversify into property and operating ports. It also has a growing involvement in Russia.
