Pros
You get to work with the poorest and most disadvantaged children in Singapore. Even though they don't explicitly say it, you are in the social service sector. And therefore, majority of parents' expectations are not that high - which translates into a lesser burden of keeping them updated on the child's progress. You may have alot of free play into deciding how things are run in your classroom as the principal may be too busy with her admin work to check on you. You finish work latest at 5.30pm. The company will organise alot of workshops / learning journeys for you to attend and upgrade your skills for free. Each centre has allocated funds to spend on learning resources. If thing gets too old and tattered, its highly possible to purchase a new one, instead of making a DIY replacement due to budget constraints. Facilities are continually upgraded and so you need not fear having things breaking down.
Cons
Very disorganised and clueless about employee satisfaction, motivation, and retention. The working environment for a kindergarten teacher very much depends on the centre's principal and the existing teachers. If they are veterans, you're in good hands. If not (which is not uncommon with the high turnover rates), then you would have to survive on your own as everybody else has their own problems to deal with. There isn't much mentoring / coaching available unless you seek it out and manage to find someone to help you along. Because kindergartens have 2 sessions - morning and afternoon, and each session having 18 to 20 children, you might have to spend time after your last dismissal (after 5.30pm?) to prepare for the next day. Apart from Nursery children, K1 and K2 classes may not have an assistant teacher around. So you need to be able to have solid classroom management skills if you got 20 children under your care. Because the central curriculum isn't perfect, there may need to be alterations to it. and every alteration needs to be recorded in a lesson plan, weekly plan, scheme of work, term plan. So, if you are good in creating and drafting out plans, its a breeze for you. If not, this is a pain point for many existing and new teachers alike. Teachers are required to participate in community events after work hours like festivals and celebrations, and most of the time, prepping the children for some show for the public. Unless you love performance art, this puts an additional strain on your part. When term starts, there is a rush to things to be done. Its hard (but not impossible) to cater for differentiated learning, because the goal of the organisation is for quantity teaching, not quality teaching.
