The day strike by public sector workers concerned about their pensions saw a march and pickets at various locations in SE1.
Striking lecturers from London South Bank University were joined on Thursday morning by teaching staff from elsewhere, including Kingston University, for a gathering in Ontario Street at Elephant & Castle.
There were cheers of solidarity as they passed Public & Commercial Services Union pickets outside the Department of Health's Wellington House building.
Slogan sheets specially printed for the SE1 marchers included the chants:
Stop your sell-offs
And pensions hikes
Then shove off
On a Boris bike.
Cameron and Clegg
You've got it wrong
Won't be long!
Court sittings at Inner London Crown Court and Southwark Crown Court were disrupted during the strike action.
There was also a picket line outside the Equalities and Human Rights Commission in Tooley Street.
In Lambeth Road police officers were drafted in to answer 999 calls at the Met's central communications command as the civilian call handlers were on strike.
St Saviour's & St Olave's Girls' School and London Nautical School were both closed.
