Are the P&O Ferries mass sackings a result of Brexit?

Analysis: UK government claimed EU exit would let it change employment law, but it has not yet done so

To the layperson, the unceremonious sacking of 800 P&O Ferries workers may look like a consequence of Britain leaving the EU, with any legal action by the trade unions turning into the first big test of workers' rights post-Brexit.

Despite Boris Johnson's assurances that Britain's departure from the EU would be better for UK workers, there have been fears it would be seen by the government as an opportunity to erode workers' rights in a bid to increase competitiveness.
