I previously worked in a hospital lab but have since resigned.

It's pretty much a routine job, there are several benches and you will rotate around the different benches depending on the roster. You will get to learn the different instruments and most of the time you feel like a robot going through motions day in day out. Not to worry about the assays and analysers as there will be training given and one has to pass the competency before you are allowed to perform the tests alone.

Pros:
-Stable industry, bonuses and increment are pretty much standard every year, so you don't have to worry about company going bust and not paying bonuses.
-Permanent position for most staff.
-Easy to job-hop to other labs since all hospitals have a clinical chem section, but do note that there is no pay increment if you jump from one public hospital to another. This is an unspoken rule.
-Don't have to bring work home to do most of the time, since it's a operation role, once you handover your shift, you can shut off.
-Reasonable number of leave at 21 days, as your number of years of service increases, it can go up til 25 days or even 28 days (for higher job grade).
-Apply to do Masters and get sponsorship from hospital, in return, you will be bonded for a number of years.

Cons:
-Clinical chemistry labs are 24/7, so you have to do shift work, including working on PH and weekend. 3 rotating shifts, morning shift, afternoon shift and night shift. You will get allowance and meals if you are working night shift/weekend/PH. You will also be asked to be on standby on certain days and if someone takes MC, then you will be called in to work.
-Leave has to plan one year in advance. If there are several people putting down the same dates, then you have to go through balloting. Hard to take ad-hoc leave as you will need to find someone to swop working day with you.
-Physically tiring as you have to be on your feet for almost the entire day.
-Mistakes made are detrimental as it impacts on patient's clinical diagnosis.
-Promotion is very slow, and you have to be exceptionally good before being considered for promotion.

For the hospital which I worked in previously, the turnover rate for clinical lab is quite high, youngsters usually don't stay for long, most work for 1 to 2 years and move on. As the number of manpower decreases, staff are asked to work for extended period of time without going for a break.
