Why should anyone come and work for you at the same salary as your competitors?
Employers often complain that it's difficult to find staff and yet pay the same amount as the competition. However, if you consider the situation from the employees perspective, you can appreciate that if the pay is approximately the same, then many things you might not consider are actually quite important to a candidate.
For example, the purpose of the organisation, the role flexibility, career growth opportunity, the manager or the organisation's prestige all become critical considerations if the pay rate is similar.
