Hygiene factors
A theory that in the workplace there are certain factors that if absent or removed will cause disatisfaction, for example refreshment facilities at work or levels of pay. However the presence of these factors won't in themselves increase satisfaction. For example, free vending machines won't lead to a satisfied workforce, but removing them will cause disatisfaction.
