The appellant was employed by the respondent law firm for 21 years.
She was initially given 18 months' working notice of termination due to the firm's financial difficulties.
Three weeks later, the respondent unilaterally amended the notice, dismissing her immediately with six months' pay in lieu of notice.
The trial judge found the first notice was binding but awarded only 12 months' pay.
The Court of Appeal allowed the appeal, holding there is no functional difference between working notice and pay in lieu of notice, and the employer was bound by the initial reasonable notice of 18 months.
