Lets compare Airport and Wdland. U go watch how they work and the environment there? If you think Wdland chkpoint nice place/environment to work, be my guest.
As for posting, its no secret that staffs in the west are posted to the East and vice versa. I am just saying if one stays in the East, be prepared to be posted to wdland/tuas. I cant think of any positive points for Wdland checkpoint. Maybe those stay in the North like Wdland/Yishun wouldnt mind. But the place is toxic, imo. Be prepared. Long hours like 12 hours shift. No nite shift allowance. Ask those who work nite shift, how long/short is their rest time?
