Editor's message: In certain situations, if an employer subjects the employee to a detriment, the employee can claim compensation.
Notable circumstances where employees are protected from being subjected to a detriment include undertaking trade union activities, making a protected disclosure (whistleblowing) and exercising family-friendly rights.
Detrimental treatment includes failing to promote an employee, to provide training opportunities and to award a pay rise where these actions were expected or promised.
The amount of compensation awarded against an employer for unlawfully subjecting the employee to a detriment is generally what the employment tribunal considers fair and is not subject to a limit.
