someone who works permanently, or for a long period of time, for a particular employer as a freelancer (= someone who usually does different pieces of work for different organizations)

Both freelancers and permalancers are self-employed. 自由职业者和常态化自由职业者都是自雇人士。

Permalancers are often seen as a cost-effective alternative to full-time employees. 常态化自由职业者被视为全职雇员的廉价替代者。
