In Publicis Consultants v O'Farrell, an employee was dismissed for redundancy with four days' rather than her contractual three months' notice. The letter of dismissal stated that she would receive a severance package comprising her statutory redundancy payment, holiday pay and an "ex gratia" payment equivalent to three months' salary. Responding to a claim for failure to pay notice salary, the employer argued that dismissal letter should be read with other correspondence showing that the ex gratia payment was made in respect of the notice pay. However, unsurprisingly, the EAT found that the dismissal letter was unambiguous in promising an ex gratia payment and, even if it had been ambiguous, it would have been read in the employee's favour (under the general rule that documents are construed against the author).
