The current study is designed to research employees' career development and employee retention rate, and the Starbucks Corporation as a case reference. Thirty participants who are having working experience 3 months and above have been recruited for the current study. As a section of participants, purposive sampling has been used as a sampling technique. Mixed method design means collects and analyses the data quantitatively and also qualitatively. The current study would have Cronbach Alpha greater than 0.70 to ensure the strength of reliability. Data would be analyzed quantitively by running IBM SPSS in a systematic way while the data would be analyzed qualitatively by forming themes. Future studies should be larger the sample size and make arrangements for break time. The current study would contribute to the HRM, especially in the employee retention part.
