The employees are waving placards and flags on picket lines outside Coops Building, on Dorning Street, Wigan and Kennedy House, on Brunswick Avenue, Leigh.
Today is the second of two days of strike action by 31 drug and alcohol support staff who are members of trade union Unison.
They have downed tools for the second time - following strike action last month - in a row over the national charity failing to honour agreements to match NHS pay rises for the same jobs.
