NHS organisation Locala has confirmed it is reviewing staffing levels and jobs could go.
The not-for-profit social enterprise runs a range of non-acute health services in Kirklees.
Its areas of responsibility include health visitors, speech therapists, stop smoking support, district nursing, dental care, school nurses, foot care and physiotherapy.
It operates in health centres, surgeries and at Holme Valley Memorial Hospital as well as in the home.
The Batley-based organisation said it was being challenged to “fundamentally change the way it worked” amid “increasing financial pressure.”
A spokeswoman said a consultation had been completed and a new model would be implemented on November 1.
It may mean workers changing roles, locations and pay grades.
Job cuts have not been ruled out but no numbers have been indicated.
Locala said it needed to boost the use of technology to allow it to save costs.
A spokeswoman said: “We have embarked on an administrative review across all corporate function and business units – clinical and non-clinical.
“We have been working, initially with employee representatives and unions, and later with colleagues across the organisation since June to look for ways to reduce reliance on administrative functions.”
