How difficult is it to become a marketing manager?

Summarizing the appropriateness of quitting a job via text message: Quitting a job through a text message is generally considered unprofessional and inappropriate. It is important to handle resignations with care and respect, as it reflects on your professionalism and can impact future references. Ideally, resignations should be done in person or, if that is not possible, through a formal email or letter. This approach allows for a more respectful and clear communication, ensuring that your departure is handled smoothly and professionally.
