Another example of companies trying to hope you don’t bother to protest when they take something from you: I got a new contract from the company I sometimes do gig economy code review for at an hourly rate. The rate was about 15% less than it was before.
I emailed about it, and the initial response was oh, it was always that it may have seemed higher because of rounding, etc. Then, I emailed back saying no, my rate was explicitly set to this at this date by your boss.
The response was oh, I guess it was.
Maybe this was an accident, but this is the third of its kind in three weeks.
