Pros
Consistently worked 45-50 hours for a weekly paycheck so cash was always available. Pretty simple work if you can handle the physical stress. You can make a 15% commission on any sales of upgraded services to existing customers or sales to new customers (mostly neighbors of existing customers). I never put in much effort in the sales department because I worked another job and didn't need the extra commission money but I could see someone adding 30-40% to their paycheck every week by working at sales.
Cons
Training left a lot to be desired. Was entirely focused on techniques and logistical process. No training provided in terms of diagnosing a problem in a lawn or solving an issue. I often found myself not knowing what to tell my customers so I'd take a picture, show it to a service manager, then call back the customer. Can't imagine I instilled a lot of confidence in those customers. Your work experience also depends a LOT on the specific branch you're working out of. We rarely worked a Saturday at my branch but the other branch in the city worked over half of them. I'm told it's almost entirely due to the branch GM's ability to budget work for the week properly. So it's quite the roll of the dice if working Saturdays is a deal breaker for you.
