I think you need not worry about the sensitivity of turnover to performance
and its difference from the average likelihood of turnover due to firm
types. That's because the inclusion of the type dummies in your estimation
is already controlling for that. So you are estimating how badly a
particular firm is performing with reference to how badly the whole industry
(or firm type) is performing. You might want to include a variable to
control for the market's overall performances as well.

Quite typical, I use it to estimate the probability of promotion within the
internal labour market of a large firm.

Hmmmm... guess there are many other people on the list who are much wiser
than me on this topic.
