It’s important to note that most people don’t move for money. Motivation for career change often comes from a desire for career progression or a need to find a culture fit that’s more suitable.
With this in mind I advise candidates to take a practical approach to salary negotiations. A good rule of thumb is to expect an increase in salary of 10% or less. Also you should think of justifiable reasons why you deserve that 10% increase. Experienced professionals often move jobs because that are primarily focused on the role, remuneration is secondary.
To be through you may want to conduct research to understand what the current market rate is for similar jobs within your industry, bearing in mind that in Trinidad and Tobago the same job could have a vastly different salary range across different industries or different size businesses.
Also remember that good negotiations are based on give and take. If you are pushing for a higher salary be prepared to work long hours to deliver outstanding performance in return.
