Most countries put the visa on the first available page that has sufficient room, which with a full page sticker/stamp would be the first blank page. You can always ask and if you have a viable reason they may put it on another page for you.
Is there a specific reason why you want your work visa on the first page? It doesn't really make a difference to immigration officals, as they are pretty adept at fanning through a passport and finding their country's visas.
