PORTLAND, Maine — The CEO of MaineToday Media says 38 workers at the Portland Press Herald are being laid off in two weeks and that another 23 workers agreed to voluntary buyouts.

In a statement, Richard Connor blamed a decline in advertising revenue for the cuts, the bulk of which are coming from the news department. Workers were notified Thursday.

Connor said newspaper revenues are tied to the national economy and that he had no choice except to confront declining revenues by downsizing the work force.

The cuts include full- and part-time workers. Connor said full-time employees who are being laid off will receive two weeks of severance pay for every year of employment.
