Unite staff at London and Eastern union headquarters took time out to demonstrate on behalf of the Palestinian people as part of the Stand with Gaza workplace day of action.
The day of action, called by StWC and CND, involved 30 minute stoppages, early morning and lunchtime protests, student protests, rallies and other actions to put pressure on the UK government to call for a ceasefire in Gaza.
For the first time three national unions, the NEU, PCS and UCU have backed workplace action for Palestine.
Among the planned actions were a student walkout in Oxford, a Greater Glasgow school strike, a lunchtime meeting of council workers in Portsmouth, a rally of lecturers and students at Manchester University, similar action at the University of Suffolk and an event organised by NUJ members outside the Sheffield Star offices.
In central London, civil servants and other workers joined a lunchtime demonstration in Parliament Square called by the PCS union.
And Media Workers for Palestine organised a protest and rally outside BBC Broadcasting House.
