National Task Force on epidemics has decided, with immediate effect, to close Uganda’s border with DRC.

@musili_andrewG Yes

@Beautifugift Is it me or, I don’t find the direct link to the application?

The Office of the Prime Minister is hiring but only hand delivered hard copies will be accepted. Nope, this is not an old advert from 1982. It is from 2026 and a government that has an e-government portal which we pay for with our tax money wants applicants from Nakapiripirit to print out hard copies of their CVs and bring them to Kampala by Bus, in 2026😳. What about Ugandans living abroad or those studying abroad? Well, I guess they can get a flight to bring their applications and then go back. Just for reference, even South Sudan and Somalia have online job application portals. And these are countries that literally depend on Uganda to exist. @OPMUganda what is this? Kale, if you don’t have IT people at OPM, a google form is literally free of charge. Mutuswaza man.
