When Does a Discretionary Bonus Become Enforceable?

Many employers use discretionary bonus schemes to reward performance and drive growth. However, a recent tribunal ruling highlights that once certain conditions are met, a discretionary bonus can become a binding obligation.

The case involved a sales incentive scheme offering employees a bonus of up to 1% of the revenue generated from qualifying new clients during their first year. The scheme required approval from a designated senior manager.

After securing a major client, the employee's manager recommended payment of the full bonus, which was subsequently approved through the company's established process. When the employer later attempted to cap the payment at a much lower figure, the tribunal found that the employee's entitlement had already arisen because the scheme conditions had been met and the authorised approval had been given.

What Does This Mean for Employers?

The ruling demonstrates that employers may not be able to change bonus terms after targets have been achieved and approval has been granted.

Businesses should review their bonus arrangements to ensure:

  • Bonus terms are clearly drafted.
  • Any payment caps are explicitly stated.
  • Approval processes are properly documented.
  • Staff understand how bonus awards are determined.

Carefully structured incentive schemes can help avoid costly disputes and unexpected liabilities.
