ABOUT 500 Sydney workers are out of work after the collapse of building firm Kell & Rigby.
Many employees and contractors have been left unpaid after the company ceased trading, the Nine Network reported.
The company has reportedly gone into voluntary administration, but is yet to make a statement.
"The company has ceased trading and we suspect that there's about 500 jobs that have gone wanting here," Brian Parker from the Construction, Forestry, Mining and Energy Union (CFMEU) told Nine.
