SYDNEY, May 16 (Reuters) - Anglo American has

frozen hiring globally after its pledge this week to simplify

the miner that is the target of a $43 billion bid by Australia's

BHP, according to an internal memo issued by Anglo and

reviewed by Reuters.

"Following yesterday's announcement of our plans to unlock

significant value through a simplification of our portfolio ...

it is appropriate that we put in place a freeze on the

recruitment of all non site-based permanent employees and

contractors across all Businesses and Group Functions," said the

memo from Monique Carter, People and Organisation Director.

Anglo American laid out plans on Tuesday to refocus on

energy transition metal copper while spinning out or selling its

less profitable coal, nickel, diamond and platinum businesses,

as it moves to fend off the world's biggest mining company.

The London-listed miner has rejected BHP twice, saying its

proposals continue to significantly undervalue the company.

Anglo American did not immediately respond to an emailed

request for comment.
