FOREIGN firms operating in Britain have been warned to treat their workers with dignity and respect by the TUC in the wake of the renewed row over calls for a boycott of P&O Ferries.

The boycott call was first made in 2022 when the firm sacked its 796-strong workforce in Britain and replaced them with overseas workers paid a fraction of their wages.

Maritime union RMT launched a boycott of P&O Ferries in response to the sackings in March 2022.
