I am 34, and am also called for the HSE Clerical Officer interview. I am an accountant and am on 28K.
If you want to earn a lot of money, and don't mind working very hard, then you are better off staying in the private sector. However, if you want a work life balance, and want the security of a permanent job, then the public sector is better. Don't assume you will automatically rise up an earn 50K or 60K anytime soon in the public sector. Just be happy to stay on the Clerical officer scale, and don't expect much more.
The reason I want to move to the public sector, is that it is very well paid for the hours you work. Also, I like office work/accounts, and I feel that I would get a better hourly rate in the public sector. I know it starts at 22K, but it rises up to 34K after 10 years. This is very good for a 32.5 hour week, little responsibility and paid overtime.
Currently I am supposed to work 40 hrs a week for my salary. I often work longer than this, and I don't get overtime or time in lieu. I am sure my hourly rate of pay is 10 euros or less, by the time I do all the extra hours. I know I would be better off emotionally by just doing a shorter week, and getting the 22K pa.
I know I could get more money in the private sector, by changing to a more senior job, but I am afraid that I would have to work even more hours and have even more responsibility. Currently I find that work can be very stressful sometimes. The feeling that I don't get adequately compensated for my efforts contribute to the stress. I resent having to work so hard for little money, after putting in so much effort to get my qualification, relevant experience etc.
Also I got made redundant a few years ago, had a number of contract jobs. A lot of these don't have sick pay. If you are out with a flu for a few days, you get no sick pay. This is difficult when there are the same household bills to pay.
The reason why I am so sick of the private sector, is because I don't have a permanent job in a large co. with sick pay, VHI paid etc. I have to work very hard for the money I earn. Sometimes I feel 'codded' because the companies pay a 'salary' say they are giving 39 hrs a week. However, they lay out so much work that I can't get it done in the 39 hrs a week. At least the public sector seem a bit more fairer.
