What are the options for renewing my stay in Thailand with an expiring work permit?

The original poster is inquiring about their options for staying in Thailand as their work permit is set to expire. Various commenters clarify that the work permit expiration does not dictate their ability to stay, as it is the 'admitted until' date in their passport that determines their stay duration. They note that by entering Thailand via an airport, a UK passport holder can receive a 30-day visa exempt entry, whereas a border run will only grant a 15-day entry, with a limitation of two per year for land entries. Additionally, they suggest alternatives such as applying for a SETV (single entry tourist visa) for an extended stay.
