Each business will be different so there is no simple answer.

My labour hiring always lagged changes in level of trade.
Trade goes up, staff work overtime until new level is proven to be sustained then add staff.
Trade declines, hold onto staff to see if trade rebounds if it doesn't then don't replace a staff member when they leave.
