At a previous company, we did have a full-time electrician. When he wasn't fixing something, he was supervising an upgrade or replacement, designing future electrical buildouts, meeting with DC tenants to be sure we didn't overcommit the electrical supply, fixing stuff around the offices, and generally being Very Useful.
To be fair, we had more than 1 data center, with complex power requirements. Much like BA, come to think....
I've worked both as a direct employee and as a contractor. A company has much more control over direct employees.
