Catherine A. Osten is an American politician and a Democratic member of the Connecticut Senate representing District 19 since January 9, 2013. Osten is a three term First Selectman from Sprague, Connecticut.
Graduating from the Norwich Free Academy in 1973, Osten enlisted in the United States Army. After four years of active duty, Osten returned to the United States, taking up residence in Norwich and attending Mohegan Community College. In 1990 Osten joined the Connecticut Department of Corrections serving for 21 years and becoming an officer.
Osten, co-chairwoman of the legislature’s Appropriations Committee, said the binding arbitration system is fair — and municipalities should accept some portion of paying for local teachers’ pensions. 
Service Employee International Union (SEIU)
As an SEIU leader and Connecticut corrections employee, Osten successful led an effort to unionize Lieutenant management. She then joined and led the effort to sue Connecticut in a class action sexual harassment and hostile work place lawsuit.
As the President of SEIU 2001 she successfully led efforts for Connecticut health care Sustinet, paid sick leave and aligning prevailing union wage and minimum wage to annual CPI increases. She was the union leader for multiple bargaining negotiations with legislative leadership and the Governor. These negotiations produced no layoffs and more spending to support essential services.
Osten joined union leaders and proposed the state of Connecticut, which underfunds their teacher and employee pensions at 42 and 55%, start and administer a retirement fund for low income workers. Local Wealth Management firms questioned the idea, "Why create a new product when knowledge is what is needed? The products already exist.”
Defined benefit plans
Osten supports a defined benefit retirement system for state employees.
Osten said she was dismayed that Norwich lost a chance to be host of an emerging high-tech industry. During a 2010 debate Selectman Osten stated, "Marijuana would be one of her top priorities."
The 2010 47th State Representative District race Coutu beat Osten 57 to 43%.
The Day newspaper stated, "He faces Sprague First Selectwoman Catherine Ann Osten, a retired corrections lieutenant who served as a union official and organizer. Ms. Osten seeks tax reform and says tax increases must be part of the budget solution..."
Osten beat Representative Tom Reynolds to win the primary for State Senate. Senator Edith Prague, SEIU, American Federation of Teachers (AFT) endorsed Osten.
The 2012 Senate race included multiple debates. In these debates there was much discussion on job creation, union intervention and the role of government.
In November 2012 Osten won the 19th Senatorial district by 51 to 49%.
In November 2013 Osten earned her third term as Sprague's First Selectman over her previous Democratic Selectman Buddy Meadows. During the campaign there was nepotism claims as Osten laid off her opponents son while keeping her son-in-law's part time position in same department. She also cut hours for the Senior Center Director, Buddy Meadows, after he announced his candidacy for Osten’s town job. In 2017, Osten was assulted by her son-in-law who, “had pushed an elderly female to the ground, spit on her and kicked her in the back.”
In November 2015 Osten earned her fourth term as Sprague's First Selectman over Dennison. Osten received a 6% increase in pay and has received three government compensations since 2012. The current salary for the full-time job of first selectman is a modest $43,901, with an additional travel stipend. She also receives a state pension of $54,174 for her years of service as a Connecticut corrections officer and $28,000, plus expenses, for her part-time job as state senator. 
On June 6, 2018, voters in a townwide referendum rejected by a 280-52 margin a combined $9.4 million education and general government budget that would have required a three-mill tax increase. Osten is focused on stabilizing Sprague's finances after addressing $1 million dollar deficit. “It’s left us with a significant problem,” First Selectman Cathy Osten said. “We have a negative fund balance, and we haven’t paid off all the bills.” The town’s fund balance — its savings account — ended the fiscal year on June 30, 2018, a little more than $1 million in the red.
