Security on the rock is patchy, however, the reason may have something to do with the long shifts and low pay rather than anything else.
I would think a look at the shift pattern and employ more staff for busy times would improve the situation.
The airport is expanding flight-wise faster than the infrastructure can cope. Perhaps it is time the Airport Board had a long look at operations and started to talk to both airlines and passengers instead of treating it as just another money making machine.
