Vary the terms of a contract where there is a term authorising the variation
Key points
An employer that wishes to vary employees' contractual terms and conditions should check the contracts to see if there is a clause that authorises the variation.
Even where there is a variation clause, the employer should exercise caution in relying on it and should ensure that the clause covers the specific change that it proposes to make.
The employer must take steps to ensure that it does not act unreasonably in exercising the clause.
