NHS workers in the Unite and Unison unions at Birmingham and Solihull Mental Health Trust struck today, Wednesday.
They are fighting a management proposal to axe their allowances in a move which most workers see as a prelude to privatisation.
Their Unite union says it will lead to workers losing an average of £1,400 a year.
The action saw pickets outside both Reaside and Ardenleigh clinics.
Strikers at the Reaside clinic, a secure mental health unit which supports vulnerable people with mental health difficulties, spoke to Socialist Worker.
'People are fed up and disillusioned about management's 'agenda for change' and we need to take a stand,” said one. “Otherwise next it will be weekend or night pay that will go.'
'It's been their aim all along to privatise us,” added another picket, 'This is like Thatcher under a different name.
“The government have made U-turns but to win we need to go bigger, we need the whole public sector out.'
