Terry Tibbs is the manager of the Tackleford municipal pool. His management style is apparently not all that popular with workers, as one day they all quit on him at once, leaving him to run the pool all by himself including being the lifeguard, as seen in the one-shot comic Human Soup, created by John Allison in 24 hours.

The interesting question is whether he is the same guy as Mad Terry, seen in some earlier strips. This Terry did seem to have a little bit of hair, while Mad Terry seemed to be entirely bald, and Mad Terry is also known for wearing a bowtie, absent from this Terry (but he is wearing a pool staff uniform, which is bowtieless; that doesn't mean he doesn't wear a bowtie when off-duty).
