What should you avoid doing when asking for a raise?

Avoid asking for a raise over an email or phone, avoid giving an ultimatum, and avoid asking during a stressful time. It's best to ask your boss in person for a raise. Doing it over mail can seem unprofessional. Giving an ultimatum can come across as too demanding and they may not give in which can result in you losing your job.

Asking at a stressful time can add more stress to your boss or manager. It's best to wait until there is a lull in the work, or when the stressful project is over.
