This is an ongoing problem in CMB, and not likely to subside anytime soon. I worked for five years with UL and the trouble did not affect crews all that much, but suggest that anyone contemplating working there to be VERY careful. The airline was pleasant to work for, the management treated expat crews quite well, altho the pay was somewhat low the route structure is excellent with many varied destinations with good layovers.
All in all, nice folks to work with.
