What amount of vacation is acceptable?
The number mandated by countries of paid vacation days varies a lot. The best would be around 30 days of paid leave + national / public holidays. These should allow members to travel home for important festivals and family gatherings, it should also give much needed rest from community chores and give you exposure to a different lifestyle.
Additional mandated vacation will occur on a regular 2 or 3 year basis, where members are sent on sabbatical or abroad to broaden their experience of the world (e50).
Finally, there should probably be a variation of days for permanent and transitory members but not too vast.
The most complicated elements would be in assuring the ‘pay’ into the savings account and holidays should only really be allowed at the end of the 6 month grace period.
What balance of time will there be between duties, research, training and leisure?
It should be as much as possible a balance between work and pleasure with exercise simply being considered as part of a daily routine. Regular sabbaticals and times of relaxation and mindfulness should punctuate the working day, week and year and these should be considered as mandatory as physical exercise.
Consistent over-workers should be closely observed to ensure they aren’t destroying themselves out of some perceived obligation; However, some people are workaholics and passionate about what they do, as long as it isn’t detrimental to their performance and health making people relax should be seen as a guideline not an enforcible standard. Work can remain a static amount but shifted between personal research, training and duties.
Study time should also be factored in outside of normal working hours. Regularly, say, every 2 years, members should take at least a month long holiday travelling and absorbing other cultures. Or a quiet retreat to friends and family, a long sojourn in a private retreat. The vacation or retreat would be subsidized by the community and the only rule is that the holiday must recorded and a journal be written of things learnt, This will then be placed into the communities library / wiki / openstreetmap e.t.c. Every map and experience will in this way help add to the whole.
