osiaikaisia

Osa-aikainen is a Finnish adjective meaning "part-time." The form osa-aikaisia is the plural partitive form of the adjective, used to modify plural nouns in the partitive case, such as "osiaikaisia työntekijöitä" (part-time workers). The term describes arrangements, roles, or individuals involving fewer working hours than a standard full-time position.

Usage and contexts: Part-time employment is common in many sectors, including retail, hospitality, education, and caregiving. Part-time contracts can be fixed-term or permanent, and the actual hours worked vary by agreement, sector, and individual arrangement. Part-time work is often chosen for flexibility, study, family responsibilities, or supplemental income.

Legal framework: In Finland, part-time work is regulated by general labor laws and sector-specific collective agreements. Rights and benefits are typically proportionate to hours worked, and employers may offer opportunities to convert to full-time when vacancies arise, depending on collective agreements and company policy. Equal treatment rules apply to part-time workers, with some caveats depending on the sector.
