Google has told its 8,000 staff here that it is recommending that those who can work from home do so because of the evolving situation with Covid-19.
The move takes effect from Thursday and will last for an indefinite period.
The company's offices will remain open however.
Some of the company's staff working in its offices in Eastpoint, Sandyford and in its west Dublin data centre will still have to come in because their workflows do not allow for them to be working from outside of the office.
Last week a majority of Google staff here worked from home for two days while tests for a suspected case of Covid-19 in an employee were awaited.
The test results found the worker did not have the virus.
The company used the opportunity to test its ability to have staff work remotely.
Earlier today, Apple confirmed that one of its employees in Cork had tested positive for Covid-19 and it was working closely with local health authorities.
Apple said:"As a precaution, we have asked some of our team members to stay at home while we work with the Health and Safety Executive to assess the situation.
"We are continuing to regularly deep clean all our offices and stores and will take all necessary precautions in accordance with guidance from health authorities."
Apple currently employs more than 6,000 staff in Ireland.
The company would not say whether the case was related to foreign travel or arose from local transmission.
