Union members in Liverpool, and across the UK, will take part in protests after P&O issued 800 redundancies.
The ferry company terminated the contracts of all their workers on Thursday causing outrage all over the country. Staff were told the news in a pre-recorded video message.
Three protests, planned by The Rail, Maritime and Transport workers' Union (RMT), will take place in Liverpool, Dover and Hull on Friday afternoon. The protest in Liverpool is set for 1pm at the Main Liverpool Port entrance (L21 1LA).

The announcement for the 'emergency demonstrations' was made on RMT's Twitter page with a post called 'Stop the P&O jobs massacre'. The union described the sacking as 'one of the most viscous examples of despotic employer behaviour'.
P&O Ferries, which transports passengers and freight, operates four routes: Dover to Calais; Hull to Rotterdam; Liverpool to Dublin; and Cairnryan, Scotland, to Larne, Northern Ireland. It has 2,200 employees remaining in the UK and began operating ferries in the 1960s.
P&O Ferries said in a statement on Thursday: "In its current state, P&O Ferries is not a viable business. We have made a £100 million loss year on year, which has been covered by our parent, DP World. This is not sustainable.
"Our survival is dependent on making swift and significant changes now. Without these changes, there is no future for P&O Ferries."
The company added that after "seriously considering all the available options", it has taken the "very difficult but necessary decision" to hand immediate severance notices to 800 seafarers.
