Relatives of people killed at work will join campaigners and supporting unions at Waltham Forest Trade Council's annual Worker’s Memorial Day.
The gathering outside Walthamstow Assembly Hall in Forest Road to commemorate the lives of men who died whilst at work will take place on April 28.
Polish man Andrezej Rokita who was killed at work in Midland Road, Leyton, in 2010 and 16-year-old Alfie Perrin who fell from a scaffold in Wansted in 2012 will be remembered.
Kevin Campbell, 46, from Poplar who was killed at the Stratford DLR site in March and Raymond Holmes a GMB member who died in 2012 on the Coppermill Thames Water site will also be commemorated.
John Cryer MP is among speakers expected to attend the event at 1pm.
Dave Knight, President of organisers Waltham Forest Trades Council said: "The United Nations say there are more people killed at work every year than those killed by war and that the majority of these workplace deaths are predictable, preventable and caused by negligent employers.
“That is why every year we mark 28 April by remembering those killed at and by work, and recommitting to the fight to stop the damage work does."
“We will be there to remember the dead, and fight like hell for the living.”
