Legal framework

On 20 March 1946, the National Council passed the Construction Workers’ Leave Act [Bauarbeiter-Urlaubsgesetz] (BArbUG), which came into force on 26 May 1946.

This law created the Construction Workers’ Leave Fund [Bauarbeiter-Urlaubskasse] (BUK), one of the first social partnership institutions in Austria. BArbUG made it possible for construction workers to earn and avail of holiday time despite changing employers and interruptions to their employment contracts. Its legal provisions built on collective agreements from the interwar period.

Over the years, BArbUG was amended numerous times and expanded to become the current Construction Workers’ Annual Leave and Severance Pay Act [Bauarbeiter-Urlaubs- und Abfertigungsgesetz] (BUAG).

BUK also gained new responsibilities, such as bad weather compensation and winter holiday compensation, and was renamed  the Construction Workers’ Annual Leave and Severance Pay Fund [Bauarbeiter-Urlaubs- und Abfertigungskasse] (BUAK).

With the founding of its own employee pension fund and its expansion into a Corporate Pension Insurance Fund (BVK) that is also open to self-employed workers, BUAK confidently entered the marketplace to face competition from the private sector.

While bad weather compensation is regulated in the Bad Weather Compensation for Construction Workers  Act [Bauarbeiter-Schlechtwetterentschädigungsgesetz] (BSchEG), the legal provisions relating to the other areas are set out in BUAG.

Since 1 January 2013, BUAK has been operating as a service provider for the Social and Training Fund [Sozial- und Weiterbildungsfonds] (SWF). In this role, BUAK collects the Social and Training Fund contribution from companies registered outside of Austria. The Social and Training Fund [Sozial- und Weiterbildungsfonds] (SWF) is responsible for funding within the context of training measures for workers or temporary work agencies.

Moreover, pursuant to § 22c  (2) no. (1) Temporary Agency Work Act [Arbeitskräfteüberlassungsgesetz] (AÜG), since 1 January  2014, BUAK has been entrusted to consult on, accept, process and decide on applications for the awarding of benefits to (former) workers who were employed in Austria temporarily and were then affected by unemployment immediately afterwards.

BUAK has also been managing another area since 2014: interim supplements paid to unemployed construction workers prior to retirement.


BUAK milestones    

The Construction Workers’ Leave Fund [Bauarbeiter-Urlaubskasse] (BUK) is founded as a social partnership institution for the construction industry.

Introduction of the requirement for companies to report their employees to BUK. This change eliminated the purchase of holiday vouchers and the need for employees to maintain a holiday ledger.

Creation of the severance pay provision for construction workers

BUK is renamed the Construction Workers’ Annual Leave and Severance Pay Fund (BUAK). Collective labour agreements gradually allowed for increasingly longer interruptions in employment contracts without loss of severance pay entitlements, and the legal regulation of the industry was implemented.

Incorporation of the bad weather compensation programme into BUAK.

Introduction of the winter holiday provision in order to improve annual employment in the construction industry.

Founding of the Employee Pension Fund to allow for a transition from the industry regulation of the construction sector to a different system of severance pay law. Inclusion of construction workers in the Employee Pension Provision (BMVG), with transitional provisions.

Addition of online services to the BUAK website. Companies are now able to enter various reports online.

Introduction of the requirement for companies registered outside of Austria to register their employees.

Transition to daily settlement of supplements.

BUAK Schulungen GmbH (Training) is founded.

The Employee Pension Fund is transformed into a Corporate Pension Insurance Fund (BVK) so that not only companies, but also self-employed workers can avail of our services (BMSVG law replaces BMVG).

A major amendment is made to BUAG in the Austrian Federal Law Gazette I no. 70/2009. BUAK’s inspection authority is expanded. Cooperation with authorities is intensified. Notification of employment contracts by employees after 8 months now only results in crediting if the companies make the required payments.

Another amendment to BUAG in Federal Law Gazette no. 59/2010, effective 1 January 2011: conversion from a holiday period of 47 qualifying weeks to a calendar year (52 weeks), elimination of the provision for replacement leave days for Saturday public holidays, increase in additional payments to 30.1%, automatic payment of winter holiday compensation to employees.

Installation of the construction site database for reporting of construction projects.

“Heat” is added as a new bad weather criterion; shift work is incorporated into BUAG; indication on the employee information (ANI) form of observed underpayment.

BUAK acts as the service provider for the AÜG Fund (Arbeitskräfte-Überlasser-Fonds, i.e. the Temporary Employment Company Fund).

Obligatory portal entry for companies. New expiry provision for the area of leave and winter holiday compensation. Introduction of holiday compensation and a new “Interim supplement for unemployed construction workers prior to retirement” area.
