Quality Personal Service Zürich AG

Quality Personal Service Zürich AG is a Swiss staffing specialist that has supported employers and candidates for more than 30 years with agile, reliable personnel solutions. Operating from Schwamendingenstrasse 36 in CH-8050 Zürich, the firm deliberately maintains a compact team of experienced personal consultants to remain close to clients’ needs, respond quickly, and deliver high-quality results. Its service portfolio spans temporary staffing (Personalverleih), try & hire (Anstellung auf Probe), and permanent recruitment (Dauerstellen), giving organizations flexible access to skilled labor and leadership while enabling candidates to explore new environments with confidence. The company’s sector focus is rooted in construction and industrial/technical domains, covering Bau Hauptgewerbe (Hochbau, Tiefbau, Holzbau/Zimmerei, Spezialtiefbau, Strassen- und Tunnelbau, Brückenbau, Sanierungen), Bau Nebengewerbe (Elektroinstallation, Heizung/Sanitär, Spengler, Lüftungs- und Kälteanlagen, Dämmungen, Stukkateur/Gipser, Schreiner, Maler/Glas), and Technik & Industrie (Metall- und Stahlbau, Rohrleitungs- und Anlagenbau, Maschinen- und Schaltanlagenbau, Kraftwerksbau/Unterhalt, Betonwarenindustrie). Beyond hands-on trades and engineering, QPS Zürich also recruits management and leadership profiles, including Kader-, Projekt- und Bauleitung, Geschäftsführung and Finanzleitung, with absolute discretion throughout the process. Temporary assignments are governed by Swiss law (AVG) and applicable GAV; employees are employed by the agency, wages follow GAV rates, overtime is paid rather than compensated, and notice periods are transparent. Weekly timesheets approved by clients form the basis for payroll and fortnightly invoicing, with overtime surcharges typically 25% (and 50% on Sundays/holidays) when not otherwise agreed. Clients provide the necessary equipment, ensure workplace safety in line with EKAS guideline 6508, and may reject a worker within the first four hours if requirements are not met, whereupon a replacement is arranged. This legal and procedural clarity, coupled with a pragmatic, service-first mindset, enables Quality Personal Service Zürich AG to deliver “Profistellen von Stellenprofis” across construction, industry, and leadership roles with speed, care, and accountability.
