Noel Cornish announced his retirement as the company revealed its plans to merge its Australian and New Zealand businesses.
Mr Cornish will step down in August and he'll be replaced by Mark Vasella who has been the President of Bluescope North America.
Mr Cornish says he'll remain involved as a member of Bluescopes board of Directors, and he admits there could be redundancies.
"Over the course of the next few months we will get more information about that and of course we will be very open and transparent about it ..let's wait and see what the detail shows and just reflect again that the way bluescope steel goes about these things that we try to have the utmost respect for people as we go through these processes." He said.
Noel Cornish says Labor's proposed carbon price will spell the end of steel manufacturing in Australia.
He says if its adopted in Australia and international competitors don't bear the same cost then Australian manufactured steel will become uncompetitive and imports will outweigh exports.
He says Labor's Carbon policy is fundamentally flawed because there will always be demand for steel.
"Australia will continue to use steel so whether its manufacutured here in australia or manufactured overseas we will still continue to use it so what we'll find is having hollowed out manufacturing in australia we will have no improvement in global greehouse gas emissions" He said.
The AWU's Port Kembla Branch Secretary, Andy Gillespie says Bluescope Steel has already cut jobs too far and production levels will be affected if more jobs go.
"I don't see there's any room for redundancies on the shop floor if the current production remains the same with the current production methods the merger of bluescope's 3 divisions i don't see affecting people on the shop floor it may however affect people higher up." He said.
