You might also consider 4 supply in very high str regions if you want to keep your guys safe but what you're doing is not gaining supplies to avoid loosing the guys who are not currently bringing supplies. If you want to avoid the full retaliations (where the haven itself) is attacked, there is no middle ground, you must have max 4 guys on any job which is really low so i would advise not doing this unless you are late in the campaign and can't be bothered to run the mission. Your haven won't grow very fast but it's one of the most deadly mini-retaliations (especially in high str regions) and it's easy to loose enough rebels that an entire month or 2 of recruitment goes to waste so growing slowly but safely is an option. I would avoid doing this for intel because 4-5 guys on intel won't give you good timers most of the time but for recruit it's an option. Sure it won't be as effective but at least you avoid one of the retaliations. The middle ground would be to know which (mini) retaliation you really hate (for most players it's recruit) and don't put more than 5 (or 4 to be on the safer side) rebels on that job with others doing another job.
having enough workers working that a retaliation could happen, but not everyone)? Is there a benefit to some middle-ground as well (i.e.
