Under the changes, Loose Women will be broadcast for 30 instead of 52 weeks. Lorraine Kelly's morning show will also be cut to 30 weeks, and will reduce from an hour to 30 minutes.
While ITV did not comment on Sawalha's views, they referred to Lygo's comments about the cuts in last week's announcement.
"I recognise that our plans will have an impact on staff off-screen in our Daytime production teams, and we will work with ITV Studios and ITN as they manage these changes to produce the shows differently from next year, and support them through this transition," ITV's managing director of media and entertainment said.
"Daytime has been a core element of ITV's schedule for over 40 years and these changes will set ITV up to continue to bring viewers award winning news, views and discussion as we enter our eighth decade."
During weeks when Lorraine is not on air, Good Morning Britain will extend by half an hour, from 06:00 BST to 10:00 BST. This Morning will stay in its slot on weekdays across the year.
In February, ITV announced that soaps Coronation Street and Emmerdale would see their content cut by an hour a week between them from next year.
Earlier this month, ITV chief executive Dame Carolyn McCall said the company was making "good progress" on a cost-cutting drive, and that she expected to make £30m non-content savings during 2025.
In the past few years, there has been a downturn in advertising revenue, part of a funding squeeze throughout the TV industry.
