The Writers Guild of America board voted unanimously to strike as of 12:01 a.m. Monday (3:01 a.m. ET), officials said.
The walkout will be the first in 20 years.
Steve Skrovan, a screenwriter for the Fox show "'Til Death," said a strike is all but inevitable.
If Hollywood writers do go on strike, late-night television hosts like David Letterman, Jay Leno and Jimmy Kimmel, as well as programs like "The Daily Show" would feel the pinch first.
Daytime soaps normally stockpile about 30 days in advance and most prime-time shows would likely make it through the end of the year without any major impact on programming.
But networks would have to resort to reruns, news programs and reality shows to fill the schedule in 2008 if a strike were to drag on.
