BETWEEN 50 and 100 workers have been let go from a Burnie's Caterpillar Underground Mining manufacturer, despite the company receiving $15 million in government grants this year.
Human resources manager Brett Smith said the workers were employed on a casual basis from an agency and were let go yesterday because of a downturn in the global mining market.
It's the second large reduction in staff this year, after about 100 casual workers were let go in February.
Mr Smith said the company relied on a significant number of casual staff so it had the flexibility to increase or decrease its workforce according to market demands.
Former Braddon Labor MHR Sid Sidebottom pledged $10 million to the plant in the federal election campaign, which he said was a redirection of funds from existing industry programs and already in the budget.
It is unclear whether the incoming Coalition government will honour the commitment.
Incoming Braddon Liberal MHR Brett Whiteley has been contacted for comment.
The promised funding was on top of a $5 million grant from the State Government's jobs and growth package.
