Usually people use the lower case with dots, i.e. `i.e.`. Also one usually uses `e.g.` in those situations with `i.e` reserved for "that is". To illustrate:
"We had to come up with some way to cut our burn rate, e.g. lay off (i.e. fire) some of our workforce; cut facilities (i.e. get out of our leases),..."
As an aside, I wish there were "minor aside" conversations that wouldn't pollute the main thread so I could respond without occupying massive comment-space.
In AE it's also usual to have a comma following them, so
"We had to come up with some way to cut our burn rate, e.g., lay off (i.e., fire) some of our workforce; cut facilities (i.e., get out of our leases),..."
The reasoning being that these expressions are "parenthetic and should be punctuated accordingly" The Elements of Style
"We had to come up with some way to cut our burn rate, e.g. lay off (i.e. fire) some of our workforce; cut facilities (i.e. get out of our leases),..."
