if present, then future。
不看句子意思的话，are given 和have been given都是可以的，但是be laid off 和 are given reason是不会同时发生的，应该是有一个先后关系，所以在if条件句中需要给出，如果他们已经被知会他们的工作安全，则他们在将来将不可以被辞退，所以B选项是不对的，如果要用are given，“ workers will not be laid off if they are been given reason to believe that their jobs will be safe"相对更make sense。
