Former Gurkha soldiers who are employed to train army recruits are set to strike for four days over job losses and zero-hour contracts. The workers are in GMB union.
They plan to have picket lines in Wiltshire, Hampshire and London. The strikes are set to take place on 29 and 30 August and 3 and 4 September.
The army trainers work for Serco which took over the contract from G4S.
Other Serco workers on Ministry of Defence contracts are at three RAF bases in Licolnshire.
They struck for two days last week against a one percent pay offer. They are members of Unite union.
