For example, a major breach could be that your wages have been rolled back significantly and you were never consulted or agreed to the reduction in wages. An example of the employer’s actions showing that they do not want to follow the employment contract would be allowing a toxic workplace to continue, despite the unwritten understanding that every employee is entitled to be treated with respect and dignity.
Please also note that not having a written employment contract does not prevent an employee from claiming constructive dismissal: in that case, we would establish your employment terms by reference to what happened in practice: your job duties, compensation, etc., and then show how elements of that have changed or been breached.
