Hi,
Don't know if you've had your question answered already... but I just wanted to say that my husband went through a similar situation a couple years back..
My husband is salaried.. (No over time no matter what). Well one day the CEO of my husbands company asked him to perform something that was out of his job description.. The item the CEO wanted done was an entire video conferencing system done for a hundred thousand dollars less than the Pros can do it for..
Anyway, so my husband (a programmer..not a video technician), had to have holes drilled into the ceiling, run wire, install drop down projector screens, a projector and make custom wood boxes for these specialty cameras... (Sound like a programmer anymore?) My husband had done these types of things to his cars to install stereos and had personal knowledge of video systems.. Nonetheless, he had never installed anything like this in his life and had to learn as he went! Kinda scary having the CEO putting that much weight on your shoulders...
Whelp in turn the CEO did not mention any compensation for the extra curricular activity.. he was too busy imagining all the money the company was going to save on airplane and hotel fees for the guys they had to fly out to have meetings.. The video system would be saving them $250,000 a year!
When 6 months of video system work went by, we realized that my husband had done over 100 hours of overtime into that specific project for no pay or promise thereof..and it was keeping him from doing his normal position..
I smelled a big, greedy fish... So I found the CA Fair labor commission and/or industrial commision (I think that's what they're called)
They stated that those that are salaried are considered 'professionals' in their field. Typically this category is for office personnel: computer programmers, office managers, dentists, drs, etc.. (no one doing any manual/phyiscal labor)...
Anyway, what it came down to was that my husband was no longer performing his professional salaried position during the hours he worked on the video conferencing system.. he was doing physical labor way out of his job description..
He brought this information to HR..(who had already told him that he would not be paid overtime due to the fact he was salaried). HR changed their tune when they heard the Industrial Commission mentioned.. They then stated that they will have to pay my husband the overtime of over 100 hours now due to the 'out of professional classification' fact alone..
My husband is now a - hourly paid - professional..
I hope your situation gets better soon with your overworking boss...
