A new survey shows that 84% of Irish organisations said they were grappling with skills shortages, an increase on the 81% reporting difficulties last year.
The survey of 500 companies was conducted by CIPD Ireland, the umbrella body for Human Resources and learning and development.
CIPD Ireland's survey shows that the worst affected sectors include IT, customer services and financial services.
Mary Connaughton, director of CIPD Ireland, said it is clear that the internal talent pipeline is a critical issue for its HR colleagues across the country.
"Our members are doing what they can through methods like succession planning and investing in their brand, but we would also like to see the government step up their efforts too," Ms Connaughton said.
She said her group are urging the Government to drive more flexible options for working and learning, while more supports are needed for those who want to re-enter the labour force at all ages too.
"Ireland's migration system must be more responsive to serve our needs more efficiently," she added.
The CIPD research also shows that 53% of members rate "flexible working" as a top priority over the next two years.
Similar numbers saw it as a way to both promote inclusiveness and address the gender gap in their organisation.
The research also examined CIPD members' feelings about the effect of smartphones on employee well-being.
Among those who feel it has a positive impact, 31% welcomed the fact that it allows more flexible working.
But on the negative side, another third complained that it prevents workers from switching off outside of work hours.
CIPD Ireland says the figures show that companies need to look at policies surrounding wellbeing at work, and the positive impact it can have on a workforce.
