Even though you work for different employers, you're still entitled to long service leave.
CFMEU WA fought hard so that on-site construction workers get to take long service leave benefits with you from employer to employer. Registered construction workers receive up to 8 2/3 weeks fully-paid long service leave after 10 years service, no matter how many different employers you've workers for.
That's 2 full months of fully paid time off. And the sooner you register, the sooner you start to acrue leave. So check your eligibility and register right now at myleave.wa.gov.au.
