My manager is still asking me for help weeks after I resigned
I was working in retail ops. My team was responsible for product displays and shelf/display tags (6k products per location × 35 locations).
For more than 11 years, the whole thing was simple: Excel >> supplier >> finished. Then this year, the design team pushed for a new "premium" template that takes more time, costs more, and the suppliers didn't want to deal with it at all. The ones who agreed were asking for around $4/card.
I spent 4 days teaching myself InDesign's data import feature, figured out the flow, and brought the cost down to 9¢/card. I told my manager that we needed to train a few more people so I wouldn't be the only one who knew how the process worked. My manager (rude, useless, insecure, and a professional bootlicker) said: "This is basically the only task you're handling. Now you want to get rid of it too?"
Then I got seriously sick and took 4 weeks of leave in June, came back, and my manager yelled at me over something he had misunderstood. It was a tiny formatting issue he was convinced I had missed.
I resigned on the spot, and sent an email to the CEO + HR saying that my manager was the reason, and I left on September 3.
Since then, I've received more than 20 calls/texts from the same people asking me to explain to them how to export the tags. I'm just waiting for my final settlement on the 22nd so I can block this whole circus.
