Hello! I understand your concern.
If you worked at McDonald's for 4 months in 2019 and went AWOL for 3 days, it seems there was a miscommunication between you and the restaurant manager. It's unfortunate that you weren't able to speak to the manager as instructed. Since you were not given a schedule afterwards and they didn't send you any notice of dismissal, it's possible that they considered you to have resigned due to your absence.
Regarding your worries about applying for a government job and whether they will be able to see your previous employment, it's important to note that government agencies have access to databases and records, including those of the Social Security System (SSS), Pag-IBIG, and PhilHealth. However, I cannot guarantee whether or not they will specifically check your previous employment at McDonald's.
If your employment at McDonald's was not officially terminated or if you have concerns about your employment records, it might be a good idea to reach out to McDonald's HR department or the specific branch where you worked. They should be able to provide you with information about your employment status and any documentation related to your resignation or termination.
Additionally, when applying for a government job or any future employment, it's generally good practice to provide accurate and complete information about your previous work experience. This includes providing the necessary documents such as employment certificates, if required.
Remember, it's always important to communicate effectively with your employers and follow proper procedures when leaving a job. This will help you avoid any potential complications in the future.
