Employee contract was terminated on 7th March. Employer and employee agreed that employee will receive two months full pay (March and April). Contract will end on 14th May. The employee's last full pay was on 29th April. So therefore the employee had already received two months full pay. Employee's P45 was processed dated 29th April. Should the employee's P45 been processed dated 14th May? If so, can the date be changed?
