The strike was called after members rejected a 2.45 per cent pay offer in the face of calls for a pay rise of an minimum of 6 per cent or 50p, whichever is the greater.
In a statement, the Harrow branch of UNISON said previously: "In Harrow Council, it is evident that there is one rate for the poor and one for the rich.
"As reported in the Harrow Observer recently, the 10 top earners in the Council received over s100,000 in 2006-2007, sickening for those staff on lower pay bands and separate terms and conditions."
