What if we could build a special building, with a role for a HR manager/overseer who would schedule mechanics to rides/power/water and make suggestions like if the staff rooms are too far from specific places or even if more mechanics are needed - there would then be less breakdown while we're trying to scenery build. It could be like - you could customise what they specialise in. Or even - you could promote one of your existing staff for the role for their area to make life a bit easier once the park gets huge but you'd still manage it yourself for a smaller park to keep costs low.
