NEO,
All that is true....very true.....but not germane to the issue.
Granted some of your countrymen see the CLA as a way of eating....drinking...making Mary on the Squire's account (some even plan to take the leftover money home on leave as a sort of "mad money" safe from the wife's clutches...) but at the end of the day it should not matter whether it is paid at source or upon arrival in country at the start of each tour. (In theory anyway!)
Perhaps the better move would be to close the company bar....ban drink....and consider any gatherings of three or more staff outside required company functions to be either a mutiny or union meeting and take disciplinary action accordingly.
In time perhaps introducing flogging as a means to raise morale will become popular again. That or require all staff to dance twenty minutes a day as Bligh did on the Bounty.
