The annual day is an opportunity for the city to remember people who have been killed or seriously injured whilst at work and is backed by the TUC and its affiliated trade unions.
This year, workers who have been taken by Covid-19 will also be remembered.
Flags will be lowered to half-mast on Liverpool Town Hall, St George’s Hall and on the Cunard Building at 11am and a minute’s silence will be held. Bells will also toll 11 times.
Staff at Liverpool City Council are being encouraged to mark the minute’s silence to remember their colleague Carol Challoner, of the leaving care team, who passed away last week from Covid-19.
Colleagues in partner organisations including the NHS and emergency services who have lost their lives in the pandemic will also be remembered.
Mayor of Liverpool Joe Anderson said: “International Workers’ Memorial Day is always a poignant day, not just in Liverpool but all across the world as we take a moment to remember people whose lives have been profoundly affected or taken from them whilst at work.
“This year we find ourselves in extraordinary circumstances. IWMD will also be a chance for us to take a moment to thank all the workers who for the last few weeks have been battling to keep the country running, keep us safe, and keep our loved ones alive.
“The pandemic will have an effect on many, many workers in our city and I would urge everyone to take a minute at 11am to reflect on their sacrifices and be thankful for their passion and skills.”
