I left Walmart in 2011 after almost 20 years, some years were good, some less so. Given the unfortunate events that started this week, nobody should be surprised with all anxiety and worry over potential job losses shown here. I will give my best advice, whether you work at Walmart or not...
Corporations are not your friend, parent or caregiver. It is a transaction, not a 'relationship'. You provide a service in return for money.
Automation is the new reality. If a robot or code can do your job, you will not have a job. Period. Do things robots can't do (it will become increasingly difficult as robots are getting better at an alarming rate)
Layoffs and periods of under/unemployment must be factored into your financial plans. Don't get into a mortgage and car loans that assume a 30 year stretch of uninterrupted income.
Save money. Don't be a fool. Save, always save. Lots. Of. Money! A six month cushion is a minimum. Eat ramen and drive a 10 year old car until you reach that goal
Note: if you have worked at Walmart for 10+ years and don't have 2 nickels to rub together, you should have a serious discussion with yourself (and a good financial planner too)...
