Correct ONLY false ones and Justify your correction

1 The reward strategy should be confidential, because declaring it to all employees will harm their morale and increase conflict as they will discover the variation in level of pay and benefits?

2 Failing to achieve strategic fit between corporate strategy, business strategy and other functional strategies will result on developing an unmeaningful HR strategy?

3 Although employees dont receive cash in benefits such as medical, life insurance or transportations but it is considered financial rewards as the company pay for it?

4 The financial rewards will produce an immediate positive effect on employees but last for a short time, by opposite the non-financial benefits will be much slower on producing positive effect but it will last for longer time?
