scholarship for sabbatical

[prabhs]

hi,
Many of us might need to go back and learn certain skills while being employed. Or some of us might also have passion towards certain subject of study or a particular area. So how can one obtain scholarships or funds or opportunities to nurture your talent that might be useful for an organization later on (for sure):
(1) Are there any scholarships offered to people while at job (if the company doesn't sponsor)
(2) Are there any grants/scholarship/ financial aid possible for a person who completed his/her higher studies, but would like to get sabbatical with a company for acquiring certain skills (could be local or overseas attachment)
3) Being more specific, if it is flavour science, how do one get a scholarship to go to learn the subject if it is not with a university but through an established flavour house. Of course direct hr emails don't work that way!
4) Are there financial aids/ travel fee related allowances possible for an unemployed person if he/she wish to pursue a particular career interest (say let it be flavour science)
5) Many scholarships are awarded to registered PhD students, however are there any scholarships to Masters program offered for a person who like to go through their passion (eg: flavour science).

thank you.
Hope many of us are looking for such opportunities.
