What happen if someone is in a management position with a contract for 38 hours a week on a salary basis, where it clarifies that overtime, weekends and public holidays, etc., were considered on that salary. However your boss rosters you for more than 38 hours a week, sometimes more than 40, and on top of that you end up doing overtime every single day due work load, which is a breach of contract. Is this legal under contract law or employment law? What are my employee rights?
