People I know take about four weeks a year. 8 weeks seems nuts. Do their managers push back all the deadlines related to their projects since they take a lot of vacation? I'd imagine managers don't even consider it and plan deadlines according to a typical (e.g., 50 weeks a year) worker output.

I haven't ever worked for a company with hard deadlines. Always enterprise software, so delays are of seemingly no consequence.

The managers indeed push back the deadlines or hire more people
