An addendum to an employment contract is a legally binding document that modifies the conditions of an existing contract between employer and employee. It provides updated or additional information, such as changes in salary, benefits, working hours, job duties, or termination procedures. When properly drafted, both parties must sign the addendum to make it official. With an addendum in place, everyone can move forward with clarity and confidence – understanding their rights and obligations in the most up-to-date terms.
