In terms of when you got paid, it depended. Most wage laborers were paid daily, but in some cases you could be paid weekly, monthly, or even yearly.
Companies were very rare, and required special licenses and legislation to set up (think things like the East India Trading Company or the Muscovy Company) because they were monopolies. So in most cases, wage labor took place between an owner-operator and their worker.
In terms of how it was thought of in class terms, it’s a bit complicated.
On the one hand, you had a significant body of journeymen who were paid wages, and they were significantly above serfs although below master craftsmen. Journeymen were legally free and no longer bound as apprentices were, they had property in their tools, they had certain rights (and responsibilities) as guild members, etc. And below the journeymen, you had a population of (unskilled) free laborers who worked for wages as well.
On the other hand, a significant percent of the population (about 4-5% in rural areas and 11-17% in urban areas) were servants. And servants had a different status than other wage workers. To quote Steinfeld:
“Servants were different from other wage workers – laborers and artificers – who occupied separate social and legal niches. Servants ordinarily were single and had not yet established households of their own. Hence, they lived with their masters and served them full time for a term. Laborers generally were married and maintained their own households. In most instances, they did not serve for a term, but worked on a casual basis by the day, week, or task…
Servants were “in the service of another.” But laborers and artificers [i.e, artisans], who did not live with their employers, might be employed by one person today and someone else tomorrow or next week, or they might…simultaneously undertake a number of different tasks for different persons.”
This distinction had important legal consequences: because they were part of someone’s household, servants were under the legal control of the master of the household; servants weren’t free to leave their employer until their term of service was up; etc.
