NEWBURGH — The office staff of the town of Newburgh has resigned en-masse.

At what was supposed to be a routine meeting Thursday of the Board of Selectmen, Town Manager Rick Briggs, Town Clerk Lois Libby and Assistant Town Clerk Jill Gilman handed in their resignations.

Part-time Treasurer Sue Lessard did not resign, but because she was an appointee of Briggs she is technically no longer a town employee.

The resignations follow a complete turnover of the board.

The Bangor Daily News says the three employees who stepped down Thursday cited a caustic atmosphere created by a group of concerned citizens who have been combing through town records and challenging officials on a range of issues.
