Ironically, in this case, something which was obviously an error on the part of the employer actually helped them, as an effective date of termination of 7 February meant that the employee’s unfair dismissal claim was out of time.
However, it is a reminder to employers of the need for careful drafting when making offers of settlement to an employee. A dismissal in the manner set out in the letter of 5 February would undoubtedly have been unfair.
If the full offer (including termination of employment) had been stated to be conditional upon the signing of a settlement agreement then, if the offer had not been taken up, the employer would still have had the possibility of dealing with dismissal openly (and fairly).
