The construction strike, which began on Tuesday, saw both sides deeply divided over pay raises and a system for piece-work pay (ackordslön).
The Swedish Construction Federation (BI) - the employers' organization that represents construction-industry interests in Sweden - even threatened a lock-out that would have affected 20,000 workers.
But the two sides agreed to leave the piece-work pay system untouched and give workers a 2.2 percent pay bump, lower than the 3.2 percent unions demanded but in line with other manufacturing industries.
The final agreement allowed both parties to claim partial victory.
"It is good that management at (labor union) Byggnads has now taken its responsibility and that we have a new agreement," Swedish Construction Federation wrote in a press release.
"The employers' attacks on our payroll system has stopped," Byggnads said in its own news release.
Byggnads took 1,650 construction workers out on strike last week though employers said that, in reality, nearly 10,000 employees were being hindered from performing their work across 500 construction sites.
