One permanent post creates 168 coverage hours every week
A post that must be occupied every minute of the week requires 168 staff-hours before leave, sickness, training or relief is considered. Two simultaneous guards require 336 hours. That simple arithmetic is only the starting point.
The difficult scheduling question is whether the specific guards who are eligible for that post can collectively supply those hours without violating the rules you configured.
- Count simultaneous posts, not just sites.
- Separate raw coverage hours from usable worker capacity.
- Count only guards who are qualified and eligible for the post.
- Model relief for leave, sickness and recurring days off.
