Can I obtain a multiple entry visa or just another single entry after leaving Thailand on a Non-B visa with a work permit?

The user is inquiring whether they can obtain a multiple entry visa or just another single entry after leaving Thailand, considering they hold a Non-B visa with a work permit valid until September. A comment advises that a new single entry permit costs 1000฿ and a multiple re-entry costs 3800฿, suggesting that multiple re-entries would be cost-effective if planning to leave and return multiple times before the work permit expires.
