This is the scenareo: Employment contract gives wrong dates for the financial and holiday year but no one noticed (about 8 yrs) and everyone, including the employee and employer have been working on the actual dates.
If this is just a simple clerical error on your contract of employment that no one noticed for years and then the employee noticed it, could they say they had to go by the word on the contract and go though the legal consultation period etc or could the employer inform them of the change?
IE: Thank you for informing us of the error on your contract. This has now been addressed and the changes made and the dates for xxxxxx now run from xxx to xxx inztead of xxx to xxx.
