Two thirds of those surveyed say having a military spouse affects their career (Picture: MOD).
A number of military spouses believe employers are not always keen to give them a job.
Research reveals they feel there's an "underlying bias" against offering them work with many hiding their background from potential employers.
The survey of more than 200 military spouses was conducted for Barclays.
It suggested that 40% of people with wives or husbands in the armed forces believed they face discrimination when applying for work.
The survey also indicated that a third had to leave a job or reduce their hours, and two out of three said having a partner in the armed forces had negatively impacted their career.
Kevin Gartside, of Barclays, said: "Our armed forces are well known for their dedication, and it's important to remember that behind the scenes they'll often be supported by an equally committed partner."
"Today's research reminds us that this commitment can lead to military spouses having to make sacrifices in their own careers or, even worse, being potentially overlooked by employers."
A Ministry of Defence spokesman said:
"Service families are a vital part of the armed forces community and we encourage companies to support the careers of military partners through the Armed Forces Covenant."
The spokesman went on to say: "We have announced a new fund to step up access to vocational training and career development for military partners, and we've recently launched a review into the support for service families, to ensure they are not disadvantaged by their loved ones' service."
