Big +1!
This is like an employer failing to gauge the number of people needed to do a job, just tell you to do a little extra...
Never ever will you get the benefit of a cut from the cost of the missing people, but your employer WILL get the benefit of delivering something more valuable to the market.
Uh,no. It's usually getting more and more work coz someone left/got fired and employer goes "well, productivity looks the same" (coz everyone is working that bit more) "why hire more?".
Or frankly you just learned more and are more productive than you were year ago... for same wage.
