  • I worked for a call center as a stop gap when I was younger. The economy had shit itself and while this company was doing great, it was looking to save money because they knew they could squeeze desperate people. Annual raises were coming up. They were based on a system heavily influenced by disciplinary action, so many of my coworkers started getting verbal and written warnings for ridiculous things.

    I finally got written up for not pulling up a reference before telling a customer about a past event. I didn’t pull the reference up because I already had it and other common topics open for easy access, which my supervisor told us to do.

    I disputed the write-up but the department manager denied it as “the information could have changed between calls, so you should have looked it up through our knowledge base”. I asked how the past could have changed and was told it doesn’t matter: it’s policy. I asked to see the policy. The goalposts immediately changed: “disciplinary action is at management’s discretion and this was a serious error in judgment”. I told them that I was shocked anyone could say that and still expect to be taken seriously, even by themselves, and refused to sign my write-up. I was pulled into the HR manager’s office and given a “Final Warning” write-up for my attitude and not signing my initial write-up. I signed that one and got on a PIP, so they were happy.

    Annual reviews were that week. I had extraordinary performance stats but got a $0.04 per hour annual raise - $83.20 per year! I walked out once I got a new job.

    I just checked: my old manager is now a “boss babe” who sells essential oils and scented candles for MLMs. Sometimes a life well lived really is the best revenge.


















  • Bingo, you got it. It only shrinks so much in volume because there’s a ton of surface area. If it was something with less surface area in relation to volume, like a sphere, it’d be much less dramatic.

    Yeah, the shipping thing doesn’t really make sense for exactly the reasons you stated. The issue is more about the temperature when the bottle is made. This is done by inflating a warm plastic tube in a mold. Cooler plastic has a bit more rebound, where it shrinks a little when the air pressure is removed. This still happens in the summer, but since the environment is a touch warmer, it shrinks just a bit less. Since a 0.5-1.0% overall change has a significant effect on the volume, you get the compensating dimple.


  • You’re welcome and encouraged to look into it yourself. You misunderstand what I’m saying and draw further conclusions based on that, though, so I can see why it doesn’t make sense. I’ll take a stab at explaining.

    I did mean surface area, not thickness. As volume decreases, so do the dimensions of the object. The thickness of the plastic is already negligible and any change within that plane is a fraction of that, so even less pertinent here. The remaining two planes of the exterior, being several orders of magnitude larger, do experience functionally significant, easily measured change. Those two planes as they relate to volume are most succinctly explained as surface area.

    I mentioned the SA:V change to illustrate that this size change isn’t visually apparent, so it’s important to adjust the volume via the dimple. This maintains a steady milk level so jugs can hold an entire gallon in the winter and ensures customers don’t think jugs are underfilled in the summer. In cold weather, the dimensions of the jugs reduce less than 1%, which means visually the change is difficult to notice, but the volume changes a fair amount, around 5%. A change in size imperceptible to most reduces the volume of the jug by about 1/20 without compensation*. By reducing the size of the dimple, less plastic can be used, which saves money.

    • This is how manufacturers can so easily fly under the radar with shrinkflation. It’s hard to see, especially since they use shapes that obfuscate these changes, but they’re easy to calculate.
