Only 17k? Nowhere near enough.
They should have looked at how long the contract had left to run in months, then worked out the compensation sum due using the monthly salary of the other two Safeskys managers in England & Wales as the base multiplier against the number of months the contract had to go, be even better if they used the sum of both managers salary which would then go a long way to making up for the salary discrimination she had experienced over the years.
