I don't drive much each week. So I only charge my Model 3 at work once or twice a week. Would it be bad to the longevity of the battery?

This would be worse for the battery compared to charging daily. Check out this chart that I found here. The top three lines (orange, purple and light-blue) show 75-65%, 75-45% and 75-25%. That means instead of following the orange line, your degradation will follow the light-blue line.
If you are charging 75-65, that's only 10% per each charge. If you are charging 85-25, that's 60% per each charge. So one 85-25 cycle equals to 6 75-65 cycles in terms of your mileage.
In other words, if you charge 85-25, that's 60% of 300, or 180 miles per charge. You can do it 2000 times (360,000 miles) before battery capacity drops to 90%.
If you charge 75-65, that's 30 miles per charge. You can do it 9000 times (180,000 miles) before it drops to 90%.
Charging 85-25 is better in the long run.
From what I can gather; I don't do much driving either as I work from home. But a plug in Tesla is a happy Tesla. Also I charge to 90 percent as Elon as mentioned and other on the board that has longer ownership. I figured 8 years warranty on battery; something goes wrong I get a new battery with new technology in a few years.

Great point. However, 30 miles X 9000 cycles is 270,000 miles, not 180,000.[/QUOTE
It's the number of charge cycles that matter, not the number of charge sessions. The chart in message #3 shows cycles. 1 cycle is when the percentages of multiple sessions add up to 100%. Charging 10 times from 65% to 75% (10x10%) or 2 times from 25% to 75% (2x50%) are both 1 cycle. The idea that the first option must be worse because 10 sessions are a lot more than 2 sessions, is wrong. In both scenarios, you get 1 cycle.
