staff member

"The lady's leg got caught at 8.45am, the first SMRT staff on the scene arrived 45 seconds later, the second one more than a minute later," he wrote.

"I understand that the morning crowd at Buona Vista can get pretty unmanageable, but there has to be more urgency. Furthermore, any talk of an ambulance wasn't even initiated until more than 10 minutes later. In my view, that's far too slow."

Shouldn't it it be" staff member" instead of just "staff"?

Thanks.
