It should be left up to the voters to elect a full-time mayor in the next election. Not some last minute deal to get a 5k monthly pension and health benefits for doing a part-time job. He only has 3 years left in his term. When he was re-elected he knew it was a part-time job. But all he needs is 3 years to get that big lifetime payout at the end. This is just a last minute money grab for his retirement. It's for him, not the town. And a 140k salary is absurd compared to mayors in much larger towns.

Edit: He also is not being transparent about what responsibilities he'd be taking on that he didn't do in the past. He says he wants to bring businesses in, but there is a separate committee for that so what have they been doing...
