Local degree holder lab tech here. Just want to highlight that lab techologists are not necessarily non-degree holders. The two non-acad tracks have also since been relabelled as Executive & Administrative (Executive) for the former, and Executive & Administrative (Administrative) for the latter.

Salary with AWS (13 months) for us (degree, lab tech) can be on par with executives (12 months), unable to verify if the bonus average differs across the two. For lab techs, on good years we can get between 1.9-2.8 months vs bad years of 1.6-2.1 months (probably even less for 2020). Agree with his mention of increments of at least 100 and above (also dependent on economy), just note that its a pre-determined lump sum increment and not a % of your salary.

That said, I do recommend degree holders to avoid taking up the lab tech jobs due to the fact that the title does not match up with your actual job scope and would be bad for your future hiring outlook. (some of us, esp degree holders, are actually operating on a level of >= Executives & Managers in the Executive track)

Agree that while salary is lower than what most local degree holders are comfortable with, the environment is relatively welcoming and not as fast paced/stressful. If you are intending to join NUS as an interim job, I recommend one to take the opportunity to further your studies as a postgraduate part-time student in NUS by making full use of the staff concession scheme.

Hope this helps.
