The worker, identified only as Tee, was arrested after he alighted the Bangkok-Sa Kaew bus in Sa Kaew’s Aranyaprathet district early Monday morning.
He allegedly stabbed Pornphan Saenprasit, 42, to death earlier on Sunday.
Police quoted Tee as admitting that he stabbed Pornphan out of anger while drunk.
He said he was fired because he was absent without notifying his employer first.
Tee was taken to Aranyaprathet Police Station at about 2am on Monday before he was handed over to Klong Luang Police Station in Pathum Thani.
