Topic: The Club House / Women working in Corrections

I need some information and feedback. I am a female CO working at a county jail in NY for 10.5 years. Out of 96 officers only 16 positions are designated GENDER SPECIFIC, female only..The administration has designated this positions 6 dayshift, 5 afternoon and 5 overnight..Due to these designations I, with 10.5 years of service will not get my shift preference due to me being #7 in “female seniority”..Male officers with 1-2 years of service will get this position..Sounds like discriminatory hiring practice due to the facility never having more than 18 female officers at one time and when we had the 18, 2 were getting ready to be let go..Any feedback or information on this subject would be greatly appreciated
