The need for consistency
[ch 10: page 323]It is a fundamental principle of fairness that rules must be applied consistently. This does not mean that the outcome will always be the same, because each employee’s circumstances are different. Even so, evidence of an employer’s inconsistency is important, especially where:
• past behaviour, for example, ignoring breaches of a rule or handing out lenient punishments, has lulled employees into a false sense of security;
• more lenient behaviour towards colleagues, or towards the claimant in the past, suggests a hidden motive, such as trade union victimisation or discrimination; or
• there truly is no difference between employees’ circumstances, meaning that different treatment cannot be justified (this will be rare).
