ST Engineering Assistant Manager reviews

Low pay. Slow career progression for the common. Politics and favouritism. Uncertain career progression. Overhead (old staff)

If job satisfaction is your primary motivator, and you’re not up for promotion, then working too hard might not actually change your performance rating. Performance grades from year to year are usually standardized (e.g., “meets expectations”), unless you're in a promotion year. Therefore, working significantly harder might not yield recognition or reward, so you might question the value of going above and beyond all the time.
