No. Your ‘brother’ electricians throw a hissy fit if anyone so much as plugs a regular power cord in an outlet. And if you let them ‘assemble’ the booth, what you get is a non-working mess that you have to sneak back in and reconnect all the network/data/video/other cables to their proper ports and locations.
And for this we have to PAY them.
Report them to the International. The International has written a Code of Excellence they want members to follow - the IBEW has fired it’s own members for not living up to it.
