WA Overpayment of Long Service Leave - Termination by Employer?

[BJT]

On the 22nd Feb this year, I was terminated from my job and and the following week received all previously accrued annual and long service leave. Almost 3 months later (22/5), I received a letter from my former employer

Hi,
I think we only got half the message. I'm guessing they are asking for some of it back claiming there was an over payment. Demand a statement / break down of final payment before you pay anything. If you have spent it in error, offer a payment plan. But get them to prove the error before you do anything.
