Robinson returned to Trinidad and Tobago after leaving Columbia University, where she re-entered the public sector in 1958. She became an economist within the People's National Movement administration of Eric Williams, the country's first Prime Minister. She next served as the Permanent Secretary in the Ministry of External Affairs from 1965 until 1967. In a June 1990 interview, Robinson revealed that in 1973 she had been offered a permanent position as the Director of Research at the Central Bank of Trinidad and Tobago. However, the government refused to release her from her contract, so she was unable to accept the job with the Central Bank. The government soon transferred her to a job St Ann’s which she later referred to as "cold storage" because of how little there was to work on at the position. "I was allegedly on special assignment having to do with the Caribbean Investment Company or something like that. In fact, it was a nothing job and I spent from ‘73 to ‘80 there on a seven-year sabbatical." Robison believed that she had been moved to the "nothing job" because her husband, A. N. R. Robinson, had fallen out with the ruling party which led to his ministerial resignation in April 1970. Robinson joined the National Institute of Higher Education, Research, Science and Technology in 1980. She served as the NIHERST's Director of Financial Institutions. In the 1980s, Patricia Robinson also proposed a ten-year development plan to implement and strengthen the Tobago House of Assembly, which was created in 1980. Her husband, A. N. R. Robinson, had served as the chairman of the Tobago House of Assembly at the time of the governmental body's inception in 1980. She retired in March 1990. In July 1990, members of the Jamaat al Muslimeen stormed The Red House in Port of Spain during an attempted coup. Several prominent members of the government were taken hostage during the coup attempt, including A. N. R. Robinson, who was the Prime Minister of Trinidad and Tobago at the time. At the height of the hostage crisis, a member of Jamaat al Muslimeen handed Prime Minister Robinson. The note, from Patricia Robinson, read simply "I love you." No one knows how Robinson was able to get the note to her husband during the Red House siege.
