Why would an increase in revenue be an implicit reason for salary increases?
Revenue could go up 10% and you’re still losing money.
It’s a valid question.
Arguing increasing profit makes wage freezes unpalatable would be more accurate.
Because increasing salary when revenue increases is a positive way to ensure employer-employee relationship is reciprocal to some extent. Otherwise people will take or not take actions to ensure that relationship gets balanced back into reciprocity. Have you heard of quiet quitting?
