Stephanie Wilkins has worked as a bio medical scientist for the NHS for over twenty years.
She claims she has been forced to join fellow NHS workers, and others from across the public sector, on the picket line in sending a message to the UK Government.
Like all those taking part in this 24 hour strike Stephanie says she doesn't want to pay more to work longer and get less.
The changes will mean that she will be £30 a month or £1,400 a year worse off.
New figures show how the number of people employed in the Welsh public sector fell by 9,000 in 2011, up until the autumn.
Over the same period, there was a rise of private sector employment of 1.2% - equating to 12,000 jobs.
The latest report from the Office of National Statistics (ONS) reveals that across the UK, a total of 276,000 people left the public sector.
