Using my highly scientific points system:
Distance of office from area you deliver to, now we are 1 per van. (0 = all duties walkable from the office, 10 = none)
Staff willing to work afternoons/change shift patterns (0 = yes, 10 = no chance)
Number of staff isolating. (0 = none/very few, 10 = lots)
Number of vacancies not filled. (0 = none, 10 = plenty)
How much your office has been squeezed by revisions in the past. (0 = 3.5 hour duties, 10 = 4.5 hours plus)
Management spreading the resources around the whole office? (0 = yes, no = 10).
Award your office a score of 0-10 for each of the above. Many of them will be 50+
