BOSTON (CBS) -Washington power players aren’t planning to talk about sequestration until Friday – that’s the day the cuts are expected to go into effect.

These cuts could affect everyone with the defense department workers taking the biggest hit.

At the Portsmouth Naval Shipyard, 4,700 civilian workers could be forced to work just four days a week through the fall.

At the Westover Air Base in Chicopee, more than 750 workers could be furloughed.

And across the country, including Boston’s Logan Airport, air traffic control towers could lose workers or be shut down entirely.

Logan Air Traffic Controller Jim Peterson says the cuts would start April 1 and last until the end of September.

“It’s going to have a ripple effect across the country,” Peterson said.

The cuts would most likely mean fewer flights and more delays as well as the closure of more than 100 towers at smaller airports.
