I worked at Big Orange off and on for about 30 years, from the mid 90's until 2015 when I had a workplace injury that resulted in me becoming permanently disabled. ( I fell down and go boom and had a TBI) The last 5 years I was full time and the front end manager.
Most of the stores I worked at, (2 in Minnesota and 1 in Colorado) a lot of the staff were from the trades. Especially in Electrical, Plumbing and Paint, or were very experienced DIYers like myself. Most were part time, some were full time. And some were department supervisors. Over that time, I did see a lot of the people who worked in the trades, return to them as the building boom increased and then return to the stores as the boom waned.
When I moved to Colorado, I was working for Vail Resorts and I managed one of the ticket offices. Since it was seasonal job, I needed work in the off season. Guess where I went? Big Orange of course. I was hired part time and transitioned to full time and then got promoted to the Front End Supervisor (FES).
In the 5 years I was the FES, I was constantly short of cashiers, even though I was paying a buck more an hour than anyone else in the valley. The same goes for every other department. We were the highest paying store in the valley, yet we were always short staffed.
We had several pro's working in our store. But, being a pro doesn't mean you are knowledgeable or ale to relate that knowledge to a customer. Luckily we did have a great one in the electrical department, and plumbing department. The pro's in building materials were failed contractors and were a bit bitter about it.
When I first started at HD, their training was not all that great. Over the years their training materials and classes improved dramatically. As well as their requirements for training. In the beginning, it was mostly pamphlets and video tapes. Later on, it transitioned to online learning and it kept getting better. HD also encouraged staff to cross train so you felt comfortable to help in other departments. Sadly, most people didn't do that. And only a few supervisors did.
Being a geek, I loved to learn as much as I could. So I cross trained in as many departments as I could. I learned to make keys, cut blinds, learn more about plumbing and electrical, sell appliances, etc. Because, as the FES, I had head cashiers who could take over if I had to go to another department to do something if they were busy or on break or something.
Over the time I was working there, demands on the staff was getting higher. We were always understaffed and the building/remodeling boom was taking off again. That meant that a lot of the more trained staff was returning to the field and leaving our store with less trained staff.
Yet, we still paid more than anyone in the Vail Valley. HD offered great benefits for even part timers. Yet we had a hard time hiring, much less keeping staff. Part of the problem was housing. Most who worked there, lived 30 minutes away at a minimum. Some lived high up which made driving in the winter an issue as the roads would often be closed due to things like avalanches or the roads not being plowed yet.
So yeah, when the building/remodeling boom is on, you will find less skilled help at big box stores. And it is not because Big Box stores are not paying enough, it is because the more skilled people are making more in the field. And, yes, you are seeing a lot of new people working in the stores. Part of it is work ethic, the younger crowd will jump ship if they don't like something you say, the hours you have them scheduled, etc. Because there is always a new job down the street. About the only place where you find that people are not leaving is Costco but even that is changing.
In the 7 years I have been gone from HD, I keep checking in on occasion. A lot of the Supervisors that were there when I was there have either left or been let go. Only 3 of the 25 DS's are left. None of the senior staff are left. I think they have been changed out 4 or 5 times.
The reason I left: I was opening the store and I was checking to see if the alarm was on for our rental area. I was up on a stack of Durock about 18" high. I was turning around to get off when my store phone rang. I was trying to answer it when something happened. I couldn't move my arms and I couldn't stop my movements. I fell of the stack of durock and I couldn't move my arms to stop my fall. I remember looking at the concrete floor thinking I was going to hit it head first and it was going to hurt. (It did) No one saw me fall but two DS's heard me fall. They later said they never wanted to hear that sound again. I was later diagnosed with a Traumatic Brain Injury (TBI) and I was eventually declared permanently disabled.
