Team of 5 and 1 person is coasting. Get rid of the 1 and you just reduced burn by 20%.
You lose the output of the coasting team member, but that's small to begin with by the scenario's setup.
If you believe coasting is contagious (why am I working so hard when clearly I don't have to like this other person), you could potentially see a boost in output.
Of course, this needs to be weighed against the risk of everyone being upset and leaving after such a decision, but in this market, that risk may be mitigated.
PS. It's really hard to make specific statements about vague hypothetical scenarios :)
