Union representatives are threatening industrial action over claims carers are being “blackmailed” into accepting split-shift working or a cut in pay.
Plans to transform working conditions for carers in Dundee went before the policy and resources committee last year but were deferred amid determined opposition from unions.
Redrawn plans – largely resembling last year’s proposals – are now back on the table.
A spokeswoman for the Dundee Health and Social Care Partnership said the proposals would allow “more focused hours with people we care for”.
Staff have been served notice of consultation, outlining new work patterns of 30 or 25 hours a week for split shifts.
Single shift options would be reduced to 23, 14 or 12 hours a week, leaving carers who want to avoid split shifts facing a wage cut of up to £4,500.
One spokesman for the GMB Scotland union called it a “horror show”.
The pay cut would come with a “financial incentive” of a one-off, £1,000 payment to any worker moving to split shifts.
The council is also expected to offer voluntary redundancy or early retirement packages.
GMB Scotland organiser Helen Meldrum described it as “emotional and financial blackmail” of low-paid women in the home care service.
She said: “We say that plunging hundreds of women into poverty pay is not a prescription for the delivery of essential public services in future.
A spokeswoman for the partnership said it was working with Dundee City Council and NHS Tayside to provide services in more sustainable ways for the growing number of frail older people across Dundee.
