A Tasmanian union is concerned hundreds of workers have been left in limbo after the closure of the Pontville Detention Centre near Hobart.
Asylum seekers were moved out of the centre just over a month ago and 250 employees were offered voluntary redundancies last week.
Helen Gibbons from United Voices says the Federal Government is yet to confirm how many redundancies will be approved and when they will be received.
She says some workers will keep their jobs but even that number remains unclear.
“The facility has been put into hot contingency; it means it has to be kept clean, it has to be kept secure, it has to be kept functional in case the government ever decides to change its mind about Pontville,” she said.
“So there will be a core staff who will have to manage that. I wouldn’t image it would be much more than a dozen people.”
