A Workshop is a facility in XCOM 2.
Staffing an Engineer in this facility opens up two special GREMLINs which can be used to staff Engineer positions in adjacent facilities (not diagonally); for this reason, workshops are most useful when built in the middle column of the Avenger, rather than on one of the edges.
