I have not read any of the other reviews here, but I will I be honest as I can about any 'cons' working at Costco:
Nights and weekends. you give that up. At least until you make it to the top of the totem pole in your dept.. That can be hard if you are in a big dept like 'front end' or in a dept. where employees have been there for a long time. You can ask to have more opening shifts and maybe a weekend off. But be careful asking for Sunday off (Sunday pay is time and a half). If you are trying to have a family, it is rough working nights and weekends. That is why I went to a different career path. Wife worked 8:30 - 5 m-f. and I wanted to as well. But I know Costco employees who make it work.
Favoritism/Friends - I don't see that much. But I know it exists. Costco recognizes that. Their warehouse managers and warehouse manager assistance are rotated with other warehouses to prevent that. However, lower level management usually aren't. I can see how they can create a relationship with their employees. It's honestly just human nature. But it is also unintentional in my opinion. It is your responsibility to recognize that and report it if you feel like you aren't being treated fairly. Costco has an open door policy.
Tardy's- That is the only thing that bothered me. If you are late more than 3 times in a 30 day period, you will get written up. This has bit me in the butt a couple of times being that I didn't get out of class in time for whatever reason. Its easy to loose track how many tardy's you have sometimes, but it is your responsibility.
The upside to that is, write ups fall off your record after 9 months.
Their policy is, if you get written up 3 times within 9 months for the same thing, you will get suspended. if you get written up 4 times within 9 months for different things, you will get suspended. They make it hard to get suspended. You have to be a joke to loose your job at Costco. If you notice you are not able to make your shift on times, it is your responsibility to let you supervisor/manager know to work with you on your shift so you are not late.
No call/no show - this is also something that bothered me, but understood why it is like that. According to the handbook, you have to call in no later than an hour before your shift or it is considered a no call/no show. Which means, if you call in 30 mins before your shift, its a no call/ no show. And a no call / no show is an automatic write up. Again, it falls off in 9 months. no biggie. its just, even if you called, if it is within the hour, its a no call no show.
Black out days for vacation - This was also annoying working there. But not a deal breaker. Costco busiest time of the year is November and December. You cannot request vacation during November or December. So if you have a family tradition, know you may not be able to attend unless you work something out with the warehouse managers. Sometimes they might work with you, but most of the time, they might tell you 'if I let you have vaca then I'd have to let everyone have vaca'.
Inventory - Costco does their own internal inventory twice a year, and the week inventory falls on, you will not be able have that week off. For instance, lets say inventory for your building is the second week of February, more than likely, you won't be able to take that week off. And you for sure will work inventory day. Whether you are running the business, counting that night. So if you anniversary or birthday is on inventory day, the best you can do is just ask to run the business so you can celebrate that night instead of counting inventory after the store closes. If you are counting inventory, your shift will most likely be 6pm-2am. However, inventory is not miserable. It can be fun, especially if you like counting. They do feed their employees who are counting with good food. Also, know if you are eligible for bonuses, you get your bonus on your check shortly after inventory. Which is a good way to keep tract when inventory is, or when you get your bonuses.
My cons are not really cons. Like I said, I haven't read any of the other reviews. I am sure most of the bad ones are from losers who couldn't hold a retail job and wanted to come here to talk down about Costco. Like I said before, It is hard to get in, but it is hard to get fired. You have to be a loser to get terminated form Costco.
I know I wasn't going to make Costco a career because I was in college. So I wasn't striving to be a manager, even though I did become a part time supervisor in the end. I loved working at Costco. I always knew, had I needed to, I could have made Costco my Career and been happy. I just didn't want to give up my nights and weekends with my wife.
Costco is a retail store, but it is not just a job. You can make it a career and become a manager in a dept. making about $60k a year. Or a supervisor making about $40k-$50k a year. you might have to just give up your nights and weekends for it.
