Union uses Border Force as 'battering ram'

Immigration Minister Peter Dutton has accused a union of using Border Force staff as a "battering ram" against the federal government in a continuing pay row.

Community and Public Sector Union members will walk off the job for 24 hours on Friday at international airports and ports across the country, with expected delays for travellers.

"They are using Border Force staff as a bit of battering ram for the rest of the public service," Mr Dutton told 2GB radio on Thursday.
