Fixed term contracts don't fall under unfair dismissal rules so can be ended at any time by the employer
Employers cannot refuse resignations from employees
I can find plenty of legislation around what employees are entitled to as pay outs when leaving employment but can't find anything about being liable for employers costs to replace them.
Care to point me to the relevant documents?
Fixed term contracts don't prevent an employee from pursuing an unfair dismissal claim IF it is ended by the employer before its stipulated end date.
