Which of the following statements about employee rights upon dismissal is TRUE?

The statement that all employees have the right to challenge their dismissal in an employment tribunal is true because employment law often provides mechanisms for employees to seek redress if they believe they have been unfairly dismissed. Employees can bring claims for unfair dismissal to an employment tribunal, and this right is generally applicable to a wide range of employees, although the specifics can depend on various factors, including the length of service and the nature of the employment contract. This right serves as a critical protection for employees, allowing them to contest decisions made by their employers that they perceive as unjust.

In contrast, the other statements do not accurately represent the legal framework surrounding employee rights. For instance, while it's true that some employees may not receive notice in certain circumstances, such as gross misconduct, the expectation generally is that employees do have a right to notice or pay in lieu of notice. Additionally, claims for emotional distress in wrongful dismissal cases may not typically be recognized unless specific circumstances apply, such as discrimination or breach of contract affecting mental well-being. Finally, while employers can dismiss employees without cause in some jurisdictions, they often must provide notice or payment in compensation, making that option conditional rather than universally applicable.
