Former colleagues are individuals who previously worked together in the same organization or team. They may have shared responsibilities, collaborated on projects, or participated in meetings. The relationships formed during this time can vary from professional to friendly, depending on the dynamics of the workplace. After leaving a job, former colleagues may maintain connections through social media platforms like LinkedIn or Facebook. They can provide valuable networking opportunities, references, or support in career transitions. Staying in touch can also lead to potential collaborations in the future, benefiting both parties professionally.
