On the other hand, if that fired worker was working 2 jobs just to afford rent, but keeps their other job and now makes enough per hour to get by doing just one job - and can spend more time with their family or studying or whatever - that isn’t necessarily so bad. Not to mention that more disposable income in the area likely means more people spending more money at your business. Chances are that not only your revenue will go up enough to employ that 10th person, but that the workload will increase enough that you’ll need the extra pair of hands.
