The government is blaming a large part of the labour shortage on the fact that many people over 50 have been "economically inactive" since the pandemic. They are hoping to persuade many in this group back into the workforce.
There is a strong possibility that some over 50s will have to re-enter the job market part time because of the COL crisis. However employers are going to have to alter their ideas about what to expect from older workers. For roles which are very physical you cannot expect a 50-60 year old to have the same physical stamina as (say) a 25 year old.
There is also the factor that some older people who may return to work will find themselves pulled into a higher tax bracket because of the stealth tax changes. There would be little incentive for them to formally re-enter the job market of they are going to be hammered by PAYE.
An interfacting question for all you expert sewers out there!
