Protests have been held at Rolls-Royce factories across the UK in support of employees of the plant in Bootle which could be shut down.
200 jobs will be lost if the plans go ahead to close the factory which makes turbines for the oil and gas industries.
Ian Tonks, Unite national officer, said: "It is scandalous that a global employer like Rolls-Royce can abandon its loyal workforce and shift production abroad. We are doing everything in our power to defend our members' jobs on Merseyside."
He added that the union will take on any company that "attempts to exploit the UK's weak employment laws because it's cheaper, quicker and easier to cut jobs here".
Protests will last for half an hour and are taking place in Bristol, Coventry, Derby, Sunderland, Barnoldswick, East Kilbride and Inchinnan as well as Bootle.
Rolls-Royce recently announced it has won a £138 million contract for Trent 700 engines. Parts of the engines will be built in its Renfrewshire plant.
