I prefer to work in different workplaces.
Working in different workplaces can be a plus in many ways. A varied job experience gives you a diverse skill set that can make you valuable to an employer.
An important additional perk is that it's often esier to get a raise by taking a higher-paying job than it is to negotiate one with a current employer.
Your experience also gives you a better ability to appreciate an excellent workplace with a pleasant boss and good salary benefits
