A survey of more than 600 officers across the region has identified substantial concerns about employment conditions and staff wellbeing at Thames Valley Police.
Among the respondents, 27 per cent said they planned to leave the force either within two years or at the earliest opportunity, while 25 per cent reported being satisfied with their role.
The Police Federation Pay and Morale Survey also found that 93 per cent believed their pay did not fairly reflect the demands of policing.
A further 78 per cent were dissatisfied with their total remuneration and allowances.
Aileen O’Connor, chair of Thames Valley Police Federation, said the proportion intending to resign exceeded the national average and placed the force among the highest in England and Wales.
She also noted that more than two-thirds considered their workload excessively demanding, a proportion likewise above the national figure.
Annual leave was identified as a particular issue, with 83 per cent of officers saying they had been refused leave.
This figure was 23 percentage points above the national average.
A separate survey response indicated that 85 per cent had experienced a rejected annual-leave request.
Work-life balance was another recurring concern.
Fatigue had affected family or social life for 79 per cent of respondents, and 57 per cent had abandoned personal arrangements because of work commitments.
The mental-health findings were similarly serious.
Eighty-two per cent reported stress, low mood or anxiety during the previous year, while 42 per cent characterised their role as very or extremely stressful.
Forty-seven per cent had sought assistance for mental-health problems, and 68 per cent judged the force’s wellbeing provisions to be inadequate or in need of development.
A further 68 per cent said they did not feel valued within Thames Valley Police.
Meanwhile, 71 per cent said they would advise against pursuing a policing career.
Ben Snuggs, deputy chief constable of Thames Valley Police, said the results reflected significant pressures affecting officers throughout the country rather than being confined to the region.
He said the force took these concerns seriously and was committed to helping personnel with their wellbeing, safety and ability to serve the public.
He added that attention would continue to be given to workload, wellbeing, safety, financial resilience and morale, with the aim of providing staff with appropriate support in both their personal and professional lives while maintaining a high standard of public service.
