Hey @FastWayne, thanks for making those points.
I learned the hard way - commuted to one job in slacks because it wasn't too far, but it didn't take too many trips to realize they were wearing at the saddle contact points. I opted to wear sturdier slacks for commuting and purpose-built jeans (like Levi's commuters) when we were allowed to wear jeans (relaxed Fridays).
But yes, agree a change of clothes is best. When I commuted further, it was to a job with a shower, so I could wear cycling clothes to and from and shower up and dress for business when I got there.
