BIG Filing for Chapter 11 and Ceasing all Operations, page-309

Correct. There are protections for employees - unpaid wages and entitlements, but not bonuses (note, this is the rule in Aust).

Directors of the company (although still employees) are excluded.

You should contact the accountant of the company first, but if the administrator/liquidator have been appointed to the company - speak to the Administrator/liquidator, to find out your unpaid hours or unpaid wages and entitlements.

And they can even direct you, to the right Gov body to make your claim.
